Abstract

Magnetic properties of lanthanum manganites of the perovskite structure, doped with calcium and strontium in various ratios, were studied. Magnetic dilution experiments and analysis of the temperature and concentration dependences of the magnetic characteristics showed that the properties of the manganites under consideration nonmonotonically depend on the Ca-Sr ratio in the lanthanum sublattice.
