Photoacoustic investigation of the temperature and magnetic-field dependence of the specific-heat capacity and thermal conductivity near the Curie point of gadolinium
(1995-11/01)
The photoacoustic technique was used as a simple but accurate tool to simultaneously determine the specific-heat capacity C and thermal conductivity K of gadolinium in the neighborhood of the Curie point. One polycrystalline ...
Depth-dependent static shielding of an impurity by a quantum plasma in a magnetic field
(1984-05/15)
The static shielding of a charged impurity embedded in a quantum plasma is studied with the use of linear-response theory. The required response function is calculated in the random-phase approximation with a uniform ...
Universal correction to scaling amplitude ratios for inhomogeneous ferromagnets with continuous symmetry
(APS through AIP, 1996-05/01)
Critical exponents and amplitude ratios for corrections to the scaling limit are calculated for a randomly diluted, weakly inhomogeneous O(m) Heisenberg model in an expansion in =4-d. Calculations for the exponents and ...
Linear-response function of a semi-infinite degenerate plasma in the presence of an external magnetic field
(1984-06/15)
The static linear-response function x0(r,r') of a semi-infinite, degenerate plasma of noninteracting electrons is calculated in the presence of an external magnetic field perpendicular to the surface. The surface is simulated ...
Nonlocal exchange energy of many-fermion systems of arbitrary dimensionality and interparticle interaction
(1986-11/15)
The exchange contributions to the ground-state energy of an inhomogeneous many-fermion system of arbitrary dimensionality are calculated. Explicit results are given for both the local-density approximation and the lowest-order ...
Critical magnetic susceptibility of gadolinium
(1988-08/01)
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 ...
Coefficients to O(3) for the mixed fixed point of the nm-component field model
(1985-10/01)
The nm-component field model has a number of application in the description of critical phenomena. The coefficients in the expansion for the stability matrix eigenvalues and correlation function exponent n for the mixed ...
Umklapp electron-electron scattering and the low-temperature electrical resistivity of the alkali metals
(1981-03/15)
The Umklapp fraction, , for electron-electron scattering in the alkali metals has been calculated using first-principles pseudopotentials. Both Coulomb scattering and phonon-exchange scattering have been included. For a ...
Critical exponents and amplitude ratios from electrical resistivity measurements of dysprosium
(1980-02/01)
Resistive anomalies in helical antiferromagnets are shown to reflect the temperature dependence of the specific heat sufficiently close to the Neel temperature. The temperature dependence of superzone energy gaps does not ...
Adsorbate densities and surface potentials of physisorbed systems: A density-functional approach
(1987-06/15)
A density-functional approach for the calculation of the density of particles adsorbed on the surface of a solid is explored including the adparticle two-body interaction. The coverages and effective surface potentials so ...
