| dc.description.abstract | 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 and the temperature dependence of 1/sf is dominated by large-momentum scattering. For TTc, 1/sf is monotonically increasing and its leading singular temperature dependence varies at t1-, where t=(T-Tc)/Tc. This temperature dependence is also present for TTc, but for Heisenberg systems, of present interest, the leading singular term varies as (-t)2--, where is the crossover exponent | en_US |
