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 ...
Dipole-dipole interactions and the critical resistivity of gadolinium
(1987-06/01)
Results are presented for the electrical resistivity of a c-axis single crystal of high-purity gadolinium metal in the immediate vicinity of the Curie temperature. Numerical analysis reveals that the data are not well ...
Effect of finite mean free path on spin-flip scattering rates near the critical point of magnetically ordered systems
(1985)
The finite electron mean free path of conduction electrons is found to play an important role in determining spin-flip scattering rates, 1/sf, near a magnetic critical point. Small-momentum-transfer processes are suppressed ...
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 ...
