Abstract

Solid solutions of lanthanum manganites with perovskite structure containing calcium and gadolinium atoms were studied by the method of magnetic dilution. The obtained magnetic characteristics and the character of their temperature changes point to a clustering of magnetic atoms in the perovskite structure. A comparison of the solid solutions under study with La1- y Gd y AlO3 testifies for gadolinium atoms taking part in the exchange interactions in the La1-0.397 х Gd0.067 х Ca0.33 х Mn х Al1- х O3 solid solutions.
