| Abstract: | We report magnetostriction measurements on Pr0.65Ca0.35MnO3 polycrystalline samples in magnetic fields up to 14 T. The charge ordering occurs below TCO=230 K. The application of a magnetic field causes the transition from the ordered insulator state to metallic state. It is found that this insulator–metal transition is accompanied by large negative jumps in the longitudinal and transverse magnetostrictions with a temperature-dependent hysteresis. The H–T phase diagram is determined from the magnetostriction. [Copyright &y& Elsevier] |
