Abstract We measured the resistivity and magnetization of La0.2Pr0.5Ca0.3MnO3 polycrystals under hydrostatic pressure and magnetic fields. With increasing pressure and fields, overall resistivity values drop sharply and the metal–insulator transition temperature increases monotonically. At the same time, the resistivity data show an anomaly developing at lower temperature than TC with increasing fields and pressure. Based on the susceptibility measurements, we suggest that this new anomaly should not be due to a thermodynamic transition but that it should be related to percolation phenomena of the metallic phase coexisting with the insulating phase.
