摘要：

Barium-doped solid solutions of lanthanum manganites in lanthanum aluminate were studied. In barium-containing magnetoresisting manganites, complete disaggregation of paramagnetic atoms does not occur even at infinite dilution, and clusters of ferromagnetically coupled manganese atoms remain in the structure.
