Abstract
The anisotropic resistivity ραα and Hall coefficient Rαβγ of La2−xMxCuO4 are analyzed as a function of x, using a rigid-band treatment of the previously given linearized augmented planewave bands of tetragonal La2CuO4. The experimental ρxx(T) is used to extract λtr=3.8, which permits a conventional electron-phonon interpretation of the high Tc. The Hall coefficients are qualitatively explained, including sign discrepancies in published measurements.
