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 ...
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 ...
