Anisotropy of the critical magnetic susceptibility of gadolinium
Geldart, D. J. W.; Hargraves, P.; Fujiki, N. M.; Dunlap, R. A. (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 ... -

Dunlap, R. A.; Fujiki, N. M.; Hargraves, P.; Geldart, D. J. W. (1994-11/15)No abstract available. -
Influence of the envelope function on the ground-state energy of quasi-two-dimensional Wigner solids
Fujiki, N. M.; Geldart, D. J. W. (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
Fujiki, N. M.; De'Bell, K.; Geldart, D. J. W. (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 ... -
Short-distance expansion for the spin-spin correlation function of uniaxial dipolar systems
Fujiki, N. M.; De'Bell, K.; Geldart, D. J. W. (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 ...
