MAGNETORESISTANCE IN THE 2-CHANNEL ANDERSON LATTICE

The paramagnetic phase of the two-channel Anderson lattice model in th e Kondo limit is investigated in infinite spatial dimensions using the noncrossing approximation. The resistivity exhibits a Kondo upturn wi th decreasing T, followed by a slow decrease to a finite value at T=0. The decrease reflects lattice coherence effects in concert with parti cle-hole symmetry breaking. The magnetoresistance obeys an approximate scaling relation, decreasing towards coherent Fermi liquid behavior w ith increasing field. The magnetic field induces a Drude peak in the o ptical conductivity.
