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 ...
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 ...
