Anisotropy of the critical magnetic susceptibility of gadolinium
(1989-06/05)
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
(1992-03/01)
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 ...
Influence of the envelope function on the ground-state energy of quasi-two-dimensional Wigner solids
(1992-10/15)
At sufficiently low density, quasi-two-dimensional electron systems in their ground state form Wigner solids. In previous studies of the ground-state energy of such systems (in the absence of an applied magnetic field), ...
Lattice sums for dipolar systems
(1987-12/01)
A general method for the evaluation of lattice sums determining the effective parameters in the Hamiltonian of a dipolar magnetic system is described. The anisotropy of the Hamiltonian is examined for crystal structures ...
