    A Mössbauer effect study of the microscopic magnetic properties of Th2Fe17 and its nitride, Th2Fe17N2.6 (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 75 (1994), S. 2598-2603 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The Mössbauer spectra of Th2Fe17 and Th2Fe17N2.6 have been measured at various temperatures between 85 and 295 K and analyzed with a model that is based on the Wigner–Seitz cell environment of each iron site, the orientation of the magnetization, and the magnetic moments as determined from either neutron-diffraction measurements or band-structure calculations. Upon nitrogenation of Th2Fe17, the 85 K weighted average isomer shift increases from 0.037 to 0.156 mm/s and further the isomer shifts of the four crystallographically distinct sites increase in agreement with the increase observed in their Wigner–Seitz cell volumes and the presence of a nitrogen near neighbor for two of the sites. The nonmagnetic thorium in Th2Fe17N2.6 yields an easy axis of magnetization which, in contrast to magnetic rare earths in R2Fe17 and R2Fe17Nx, is in a general basal direction and not oriented along one of the basal axes. The isomer shift and its temperature dependence for both Th2Fe17 and its nitride are very similar to those observed in related rare-earth R2Fe17 compounds and their nitrides. Upon nitrogenation of Th2Fe17, the 85 K weighted average hyperfine field increases from 256.3 to 336.5 kOe. However, the increases on the 6c and 18f sites are smaller than those observed on the 9d and 18h sites; changes which are in agreement with changes in the magnetic moments observed by neutron diffraction and calculated for the nitrogenation of Nd2Fe17, Gd2Fe17, and Y2Fe17.

    Change of magnetic properties of Th2Fe17 due to interstitial solution of C and N : The 5th Joint MMM−Intermag Conference (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 70 (1991), S. 5983-5985

    Notes: The changes in magnetic and crystallographic properties in the series Th2Fe17Cx and Th2Fe17Nx have been studied. The changes in the latter series were also studied by 57Fe Mössbauer spectroscopy. The ultimate enhancements of the saturation moments in these series are 13% and 24%, respectively. This is much larger than observed previously in the corresponding rare-earth compounds, although the Curie temperature enhancements are of comparable magnitude. In the Th–Fe–C system a novel compound of the BaCd11 type was found, having a Curie temperature around 370 K.

    Magnetic phase transition and magnetocrystalline anisotropy of Sm2Fe17CxNy : The 5th Joint MMM−Intermag Conference (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 70 (1991), S. 6015-6017

    ISSN: 1089-7550

    Topics: Physics
    Notes: Alternating current (ac) susceptibility and high magnetic field measurements were performed to investigate the magnetic phase transitions and the magnetic anisotropy fields in Sm2Fe17CxNy with x=0, 0.4, 0.7, and 0.9. An unidentified magnetic phase transition is observed in all Sm2Fe17CxNy compounds, which is neither due to a spin reorientation nor due to a first-order magnetization process (FOMP) transition. Samples of Sm2Fe17CxNy (x(approximately-greater-than)0) have even higher anisotropy fields than are found in Sm2Fe17Ny.

    Influence of Mn substitution on the magnetic properties of Ho2Fe14C compounds (1990)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 67 (1990), S. 4774-4776 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The crystallographic and magnetic properties of the compounds Ho2Fe14−xMnxC have been investigated by means of x-ray diffraction and magnetic measurements. Magnetization measurements made in fields up to 38 T showed that the saturation moment exhibits a minimum at a Mn concentration corresponding to about x=2. The occurrence of this minimum is explained by antiparallel coupling between the Ho and 3d sublattice magnetization, the latter becoming strongly reduced with increasing Mn concentration. Most of the Ho2Fe14−xMnxC compounds investigated have a break in the magnetization curves measured at 4.2 K. This break is interpreted as the onset of decoupling between the antiparallel coupling between the rare-earth and 3d sublattice. A mean-field analysis was used to derive the intersublattice molecular-field coefficients nRT.

    Quantitative analysis of nonlinear microwave surface impedance from non-Lorentzian resonances of high Q resonators (1996)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 67 (1996), S. 3757-3758 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A method of analyzing the response of nonlinear high Q resonant circuits, such as superconducting microwave cavities, is presented. The method enables one to extract the nonlinear surface impedance, Zs(Hrf), from the complex transmission amplitude, S21(f), as frequency, f, is swept across the resonance. Sensitivity to small changes in the microwave field strength (ΔHrf〈1 mOe) can thus be obtained. © 1996 American Institute of Physics.

    Substrate dependence of Kondo and local moment physics in thin metal films (invited) (2000)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 87 (2000), S. 6079-6082

    Notes: Recent experiments have revealed that Kondo behavior in reduced geometries can be quite different from that found in the corresponding bulk systems. For example, the Kondo contribution to the resistivity in thin metal films can be suppressed by reducing the film thickness. This behavior has been explained theoretically by Zawadowski and co-workers [O. Újsághy, A. Zawadowski, and B. L. Gyorffy, Phys. Rev. Lett. 76, 2378 (1996); O. Újsághy and A. Zawadowski, Phys. Rev. B 57, 11598 (1998); 57, 11609 (1998)]. in terms of a model involving a surface induced single ion anisotropy at the local moment site. Moments which are near a surface experience a splitting which can result in a nonmagnetic ground state. In this article we describe experimental observations regarding such surface effects, and in particular the influence of the substrate on the Kondo behavior. We find that with substrates of freshly oxidized Si or freshly prepared SiO coated glass, the Kondo effect can be much larger than when the same film is deposited on glass. This finding seems to resolve a long standing controversy in the field. © 2000 American Institute of Physics.
