Abstract

The electrical resistivity of the small-bandwidth manganite Pr _0.7Ca_0.3MnO₃ as a function of temperature and pressure was investigated. It was observed that pressure in the range above ∼2 GPa induces much more complicated changes than in the low-pressure range, in which pressure only enhances the metallic state. It was found that the metal-insulator transition temperature increases with pressure below ∼3.5 GPa and decreases above ∼3.5 GPa, and the system becomes a ferromagnetic insulator at higher pressures.
