Magnetic phase transitions in the bismuth-containing manganites with perovskite structure

Abstract

The magnetic properties of solid solutions based on lanthanum and bismuth manganites were investigated. It is established that the substitution of ions by ones causes the transition from the ferromagnetic to the antiferromagnetic state while is a ferromagnet. The results are explained in terms of the superexchange interaction via anions and local distortions of the crystal structure.
