    Critical behavior of amorphous (Fe1−xMx)90Zr10 alloys with M=Co, Ni, and 0〈x〈0.04 (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 61 (1987), S. 4401-4403

    Topics: Physics
    Notes: From the critical behavior of the magnetic inhomogeneous (Fe1−xMx)90Zr10 amorphous alloys, where M=Co and Ni, the critical exponents α, β, γ, and δ are derived. Their values are rather large, strongly deviating from the theoretical ones in the case of an ordered 3D-Heisenberg spin system. This behavior is probably due to the magnetically inhomogeneous character of these alloys, as evidenced especially in previous Mössbauer and magnetic studies.

    59Co spin echo NMR in the Co3−xFexB system (1987)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 61 (1987), S. 3650-3652 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: 59Co nuclear magnetic resonance (NMR) was studied by a spin echo technique in a series of Co3−xFexB (0≤x≤1.5) crystalline compounds in zero magnetic field at the temperature of 4.2 K. A revised interpretation of 59Co NMR spectrum in Co3B is given, based on the theory of NMR inside the domain wall. Iron was found to cause reorientation of the easy axis in Co3B.

    A 57Fe Mössbauer study of Nd2(Fe1−xCox)14B (1987)
    [S.l.] : American Institute of Physics (AIP)

    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A Mössbauer study of the compositional series Nd2(Fe1−xCox)14B confirmed the preferential occupation of j2 sites by the Fe atoms at least for x〉0.6 and the strong dependence on x of the relative amount of Fe distributed on this type of site. The j2-site preference of Fe also influences the hyperfine field of Fe at the j2 site as a consequence of the higher concentration of Co around the j2 sites as compared to that of a statistical distribution.

    Specific heat of amorphous Ni80−xFexB16Si4 alloys (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 57 (1985), S. 3551-3553 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The specific heat of amorphous Ni80−xFexB16Si4 alloys has been measured in the temperature range of 1.5〈T≤25 K with 0≤x≤19. Assuming a Gaussian distribution of Schottky terms the specific heat was described satisfactorily in the whole temperature and iron concentration range. Anomalous behavior of θD and N(EF) was found near the critical concentration xc, for the onset of ferromagnetic ordering. The entropy Sm determined from the Schottky-like contribution of the specific heat shows a maximum at xc.

    Wave-induced plasma transport in the magnetic drift frequency range (1985)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Fluids 28 (1985), S. 538-543 
    Details
    ISSN: 1089-7666
    Source: AIP Digital Archive
    Topics: Physics
    Notes: A calculation of the quasilinear transport and heating of plasma particles and diffusion of particle energy is presented, emphasizing the resonant interaction of plasma particles with waves in the magnetic drift frequency range. Substantial transport can occur for relatively small wave field amplitudes in a number of applications involving tandem mirrors and ELMO Bumpy Toruses (EBT), e.g., pumping of thermal barriers in tandems and profile control in EBT's. The diffusion is selective and can cause preferential transport of a particular charge or energy component, and can even be inward in some cases.

    Differential ac method of thermopower measurement (1986)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 57 (1986), S. 3053-3058 
    Details
    ISSN: 1089-7623
    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A new differential ac technique is described for rapid and continuous measurement of thermoelectric power of thin metallic ribbons over a wide temperature range. Sinusoidal heating of one thermocouple junction by means of a small resistive heater results in a measuring principle which eliminates spurious thermoelectric voltages in the lead wires and favorably benefits from ac signal processing. The resultant equilibrium temperature of the heated junction contains a constant term depending on thermal parameters of the system, and an oscillating term with a frequency-dependent amplitude. By choosing a suitable sample configuration no corrections are required for the thermal response of the system. By careful shielding of the measuring circuits and using modern lock-in amplifiers noise voltages can be reduced to less than 1 nV for measuring frequencies below 10 Hz. Measurements accurate to 1% are possible, using temperature differences smaller than 10 mK. The effectiveness of this technique is demonstrated by comparing our measurement of the thermoelectric power of an amorphous Fe80B20 alloy with measurements using conventional techniques and by studying the thermopower of an amorphous Fe90Zr10 alloy in the vicinity of its second-order magnetic phase transition.

    Thin-film bolometer with fast response (1987)

    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: A short summary on recent developments in semiconducting temperature sensors is given. A thin-film germanium resistor is described in detail, which is used for fast and accurate thermometry in a nonadiabatic microcalorimeter. The use of only standard vapor deposition techniques makes this sensor also available to research groups lacking access to semiconductor technology. The general good performance and its good mechanical properties have the potential of numerous applications in fast and accurate low-temperature thermometry.
