Research Abstract |
Within the framework of the Kubo formula, we developed a calculation tool of conductivity tensor of magnetic materials by using the first principles technique for the electronic structure. Appling this method to the spintronics materials, we studied the effects of chemical disorder and spin fluctuation on the electrical resistivity, anomalous magnetoresistance effects (AMR), anomalous Hall effect and spin polarization.
