  • Analytical structure of the wave-number-dependent susceptibility of many-fermion systems at low temperature and long wavelength. II 

    Geldart, D. J. W., and M. Rasolt. 1980. "Analytical structure of the wave-number-dependent susceptibility of many-fermion systems at low temperature and long wavelength. II." Physical Review B (Condensed Matter) 22(8): 4079-80. Copyright © 1980 American Physical Society.
    For pt.I see ibid., vol.15, p.1523 (1977). It is shown that the nonanalytic structure of the wave-number-dependent susceptibility noted by Geldart and Rasolt is not removed by including repeated particle-particle scattering

  • Anisotropy of the critical magnetic susceptibility of gadolinium 

    Geldart, D. J. W., P. Hargraves, N. M. Fujiki, and R. A. Dunlap. 1989. "Anisotropy of the critical magnetic susceptibility of gadolinium." Physical Review Letters 62(23): 2728-31. Copyright © 1989 American Physical Society.
    The magnetic susceptibility along the c axis (xc) and in the basal plane (xb) has been measured on a single crystal of Gd in the reduced temperature range 410-4t1.310-2. Uniaxial anisotropy is observed. Magnetic dipole-dipole ...

  • Critical magnetic susceptibility of gadolinium 

    Hargraves, P., R. A. Dunlap, D. J. W. Geldart, and S. P. Ritcey. 1988. "Critical magnetic susceptibility of gadolinium." Physical Review B (Condensed Matter) 38(4): 2862-4. Copyright © 1988 American Physical Society.
    The magnetic suspectibility of a single crystal of high-purity gadolinium has been measured in the critical region with use of AC susceptibility methods. For reduced temperatures t10-3, the data are described by a simple ...

  • Diamagnetic susceptibility of a dense electron gas 

    Vignale, G., M. Rosolt, and D. J. W. Geldart. 1988. "Diamagnetic susceptibility of a dense electron gas." Physical Review B (Condensed Matter) 37(5): 2502-7. Copyright © 1988 American Physical Society.
    The authors calculate the diamagnetic susceptibility of a uniform interacting electron gas in the random-phase approximation. From this the exact high-density expansion of the diamagnetic susceptibility is obtained

  • Magnetic susceptibility of metallic transition-metal dichalcogenides 

    MacDonald, A. H., and D. J. W. Geldart. 1981. "Magnetic susceptibility of metallic transition-metal dichalcogenides." Physical Review B (Condensed Matter) 24(1): 469-72. Copyright © 1981 American Physical Society.
    A tight-binding model has been used to estimate the anisotropy of the magnetic susceptibility of the metallic transition-metal dichalcogenides. The calculated anisotropies obtained are in qualitative agreement with ...

  • Short-distance expansion for the spin-spin correlation function of uniaxial dipolar systems 

    Fujiki, N. M., K. De'Bell, and D. J. W. Geldart. 1992. "Short-distance expansion for the spin-spin correlation function of uniaxial dipolar systems." Physical Review B (Condensed Matter) 45(9): 4686-94. Copyright © 1992 American Physical Society.
    Motivated by recent work on the critical resistivity of gadolinium, a detailed study has been made of the temperature dependence of the two-point vertex function in the large-momentum regime. The operator-project expansion ...

  • Spin correlations in the low-density electron system 

    Green, F., D. Neilson, L. Swierkowski, J. Szymanski, et al. 1993. "Spin correlations in the low-density electron system." Physical Review B (Condensed Matter) 47(8): 4187-92. Copyright © 1993 American Physical Society.
    The authors have calculated the spin susceptibility x(q,) within a microscopic model over the full range of densities of the electron liquid in the paramagnetic state. Electron-electron interactions are described by static ...
