Abstract
Resistivity measurements of Eu0.58Sr0.42MnO3 were carried out at different magnetic fields under ambient pressure and 1 GPa, respectively. The critical temperature TC of the ferromagnetic metallic state is 128.5 K under 1 GPa and 7 T. The antiferromagnetic insulating phase can be transformed into the ferromagnetic metallic phase by either magnetic field or pressure. Different from the effect of the magnetic field, a plateau is observed in the temperature dependence of the resistivity curve in the lower temperature under pressure, which indicates a phase separation. Magnetic phase diagrams at ambient pressure and 1 GPa are established.
