Diamagnetic susceptibility of a dense electron gas
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
Spin correlations in the low-density electron system
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 ...
Critical magnetic susceptibility of gadolinium
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 ...
Magnetic susceptibility of metallic transition-metal dichalcogenides
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 ...
Anisotropy of the critical magnetic susceptibility of gadolinium
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 ...
Short-distance expansion for the spin-spin correlation function of uniaxial dipolar systems
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 ...
Analytical structure of the wave-number-dependent susceptibility of many-fermion systems at low temperature and long wavelength. II
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
