    Morphology and local structure in labyrinthine stripe domain phase (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1991-12-13
    Description: Analysis of globally disordered, nonequilibrium "labyrinthine" stripe-domain patterns in thin ferrimagnetic garnet films has revealed a well-defined local structure containing an oblong polygonal plaquette as the fundamental motif. Two types of labyrinths were found: one having topological defects, the other composed of a single, unbranched, meandering line. These patterns emerge when the labyrinthine state is approached either by heating at constant magnetic field or by demagnetizing from saturation at constant temperature. Size and aspect ratios of the oblong polygonal plaquettes prove to be independent of the choice of these two mutually orthogonal trajectories within the phase diagram, which is surprising in view of the different mechanisms and concomitant topological constraints governing the evolution of disorder. The significance of this unique local structure is discussed in the general context of defectmediated melting of two-dimensional stripe phases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seul, M -- Monar, L R -- O'gorman, L -- Wolfe, R -- New York, N.Y. -- Science. 1991 Dec 13;254(5038):1616-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17782211" target="_blank"〉PubMed〈/a〉

    Domain shapes and patterns: the phenomenology of modulated phases (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-01-27
    Description: A wide variety of two- and three-dimensional physical-chemical systems display domain patterns in equilibrium. The phenomenology of these patterns, and of the shapes of their constituent domains, is reviewed here from a point of view that interprets these patterns as a manifestation of modulated phases. These phases are stabilized by competing interactions and are characterized by periodic spatial variations of the pertinent order parameter, the corresponding modulation period generally displaying a dependence on temperature and other external fields. This simple picture provides a unifying framework to account for striking and substantial similarities revealed in the prevalent "stripe" and "bubble" morphologies as well as in commonly observed, characteristic domain-shape instabilities. Several areas of particular current interest are discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seul, M -- Andelman, D -- New York, N.Y. -- Science. 1995 Jan 27;267(5197):476-83.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17788780" target="_blank"〉PubMed〈/a〉

    Scale transformation of magnetic "bubble" arrays: coupling of topological disorder and polydispersity (1993)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1993-10-22
    Description: The evolution of disorder in response to period adaptation in a hexagonal magnetic bubble array is shown to arise from the proliferation of dislocations and to proceed by means of intermediate states of steadily decreasing hexatic order to an amorphous final state. Remarkably, each dislocation core imposes a size adjustment on bubbles decorating its constituent pair of five- and sevenfold coordinated sites. Topological disorder thus induces intrinsic polydispersity and converts the initially unimodal size distribution into a trimodal one. This intimate interplay between geometry and topology provides an explicit mechanism by which structural disorder arises as a result of frustration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seul, M -- Murray, C A -- New York, N.Y. -- Science. 1993 Oct 22;262(5133):558-60.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17733238" target="_blank"〉PubMed〈/a〉

    Novel design for eucentric goniometer heads: A cap-in-socket tilt stage (1988)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 59 (1988), S. 668-669

    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A novel design for a biaxial goniometric stage is described. The two stacked mutually perpendicular arc sections of the conventional eucentric goniometer head are replaced by a single tilt platform. The principal feature is the motion of a spheroidal cap in a matching socket, permitting two-dimensional tilting action about a fixed center of rotation. This design has the advantage of a significant decrease in overall height of the goniometer head, providing additional space for a variety of attachments.

    Imaging of fluctuating domain shapes: Methods of image analysis and their implementation in a personal computing environment (1991)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 62 (1991), S. 784-792

    Notes: Methods for the analysis of digital images have been implemented on a personal computer, augmented with a 32-bit floating-point array processor located in its backplane. They are applied to derive a quantitative description of domain shapes and patterns, as well as dynamic shape fluctuations, based on series of images recorded on video disk or tape. This description relies on a variety of algorithms, in part developed in the context of optical character recognition, to extract and encode domain boundaries, and to evaluate moments and power spectra of momentary boundary configurations. Time-series analysis of principal axes directions and of selected, active Fourier modes in terms of suitable correlation functions permits the study of dynamic phenomena. Examples are discussed to illustrate the scope and versatility of the analytical procedures whose wide applicability in laboratory environments is facilitated by their implementation on a personal computer platform.

    Statistical theory of X-ray scattering from crystals of finite size with pure displacement disorder in one dimension (1989)
    [S.l.] : International Union of Crystallography (IUCr)

    Notes: The statistical theory of X-ray scattering from a crystal that is disordered in one dimension is discussed. The state of disorder is characterized by probabilities that different types of scattering elements occupy specified positions. The effect this disorder has on the corresponding ensemble average axial reflections is determined. Finite size is explicitly accounted for. Motivated by recent experiments on water intercalation into thin, lyotropic multilayers, special consideration is given to systems whose components differ with respect to size, but not with respect to their scattering factors. Focusing on this case of pure displacement disorder in a binary mixture, a representation of the scattering function in closed form is derived. The case of a random binary mixture leads to the results of Hendricks & Teller [J. Chem. Phys. (1942), 10, 147- 167], and Méring [Acta Cryst. (1949), 2, 371-377], while in the presence of nearest-neighbor correlations, a connection is established with the theory of Kakinoki & Komura [J. Phys. Soc. Jpn (1952), 7, 30-35]. In extension of their treatment, systems with non-stationary transition probabilities are investigated. The effects on the scattering function of constraining composition fluctuations are also studied. Particular characteristics of the scattering function are displayed and discussed.
