Effect of finite mean free path on spin-flip scattering rates near the critical point of magnetically ordered systems
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 ... -
Universal correction to scaling amplitude ratios for inhomogeneous ferromagnets with continuous symmetry
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 ...
