Magneto-Resistance in the Two-Channel Anderson Lattice
arXiv:cond-mat/9609214 · doi:10.1103/PhysRevLett.78.2000
Abstract
The paramagnetic phase of the two channel Anderson Lattice model in the Kondo limit is investigated in infinite spatial dimensions using the non-crossing approximation. The resistivity exhibits a Kondo upturn with decreasing , followed by a slow decrease to a finite value at . The decrease reflects lattice coherence effects in concert with particle-hole symmetry breaking. The magneto-resistance obeys an approximate scaling relation, decreasing towards coherent Fermi liquid behavior with increasing field. The magnetic field induces a Drude peak in the optical conductivity.
