Abstract
The magnetoresistance and Hall effect data for polycrystalline samples of L
a2/3D1/3MnO3 (D = Ba, Sr) have been analyzed. It has been revealed that the
peculiarities of galvanomagnetic properties take place at the metal-insula
tor transition temperature which is less than the Curie temperature. The an
omalous Hall coefficient is almost three orders of magnitude larger than th
e normal Hall coefficient. The effects observed have been explained by the
shift of the mobility edge.
