- Аннотация: This paper reports on a study of the magnetic, transport, magnetotransport, elastic, and magnetoelastic properties of the R0.55Sr0.45MnO3 ceramics (R = Sm, Eu0.40Nd0.15, Tb0.25Nd0.30) with the same carrier concentration and identical tolerance factor but which differ in the cation disorder parameter sigma(2). It was found that the Curie temperature T-C decreases linearly with increasing sigma(2). An increase in sigma(2) results in an increase in the maximum electrical resistivity and an increased jump in the temperature dependence of linear thermal expansion near T-C, as well as in a decrease in magnetoresistance and magnetostriction. For T > T-C, one observes an abrupt increase in magnetostriction, magnetization, and magnetoresistance in a critical field H-C1 which grows with increasing temperature. The value of H-C1 determined at fixed T/T-C decreases with increasing sigma(2). (C) 2002 MAIK "Nauka/Interperiodica".
