Query: Transport and structural study of pressure-induced magnetic states in
  Nd0.55Sr0.45MnO3 and Nd0.5Sr0.5MnO3   Pressure effects on the electron transport and structure of Nd1-xSrxMnO3 (x =
0.45, 0.5) were investigated in the range from ambient to ~6 GPa. In
Nd0.55Sr0.45MnO3, the low-temperature ferromagnetic metallic state is
suppressed and a low temperature insulating state is induced by pressure. In
Nd0.5Sr0.5MnO3, 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.
