Magnetotransport Scaling in Anomalous Metallic Phase near the Mott Transition
Abstract
The Hall angle in the doped V2O3 is discussed on the basis of an extended Ginzburg-Landau theory of spin fluctuations. A spinon-like collective transport process beyond the ordinary quasiparticle transport theory is necessary to understand the experiment. At the same time a criticism of a quasiparticle transport theory on the basis of the fluctuation exchange (FLEX) approximation is made.
