摘要：
The magnetoresistance and Hall effect data for polycrystalline samples of La2/3D1/3MnO3 (D = Ba, Sr) have been analyzed. It has been revealed that the peculiarities of galvanomagnetic properties take place at the metal-insulator transition temperature which is less than the Curie temperature. The anomalous Hall coefficient is almost three orders of magnitude larger than the normal Hall coefficient. The effects observed have been explained by the shift of the mobility edge.
