Аннотация:Giant vokume magnetostriction , reached ~10^(-3), is found in La(1-x)SrxMnO3 (0.1<=x<=0.3) single crystals and A(1-x)SrxMnO3 (A = Nd, Sm: x = 0.33, 0.4, 0.45)ceramics near Curie point Tc. Volume magnetostriction and magnetoresistance exhibit similar dependences on temperature and magnetic field in Tc-region that is explained by the presence in these compounds of magnetic two-phase ferro- antiferromagnetic state due to strong s-d exchange.
