Negative Magnetoresistance in the Anderson Localized States. II. Effect of Electron Correlations

抄録

We recently proposed that the Zeeman shift of the occupied states leads to a large negative magnetoresistance in the Anderson localized states. In this paper we considered the effect of electron correlations in the same Anderson localized state and found an apparent linear dependence on the magnetic field of negative magnetoresistance at low temperatures, which explains the experimental data of 1T-TaS₂ by Kobayashi and Muto.
