Abstract

Pressure effects on the electron transport and structure of Nd_1−xSr_xMnO₃ (x = 0.45, 0.5) were investigated in the range from ambient to ∼6 GPa. In Nd_0.55Sr_0.45MnO₃, the low-temperature ferromagnetic metallic state is suppressed and a low-temperature insulating state is induced by pressure. In Nd_0.5Sr_0.5MnO₃, the CE-type antiferromagnetic charge-ordering state is suppressed by pressure. Under pressure, both samples have a similar electron-transport behavior although their ambient ground states are much different. It is surmised that pressure induces an A-type antiferromagnetic state at low temperature in both compounds.
