Abstract The anomalous temperature and concentration dependences of the Hall effect observed for La 2− x Sr x CuO 4 are clarified theoretically, extending the electronic structure recently derived by Kamimura and Eto to a periodic system. The calculated results can explain satisfactorily all the observed anomalous behavior of the Hall effect including the sign change. Furthermore the cotangent of the Hall angle is predicted to be proportional to T 2. It is shown that the origin of anomalous behaviors of the Hall effect is due to the warped shape of the Fermi surface.
