摘要：

Magnetic and magnetoresistance measurements were carried out on a distorted perovskite, Eu0.58Sr0.42MnO3. In the absence of applied magnetic field, this compound is an insulator down to 5 K. Results of the ac- and de-susceptibility measurements suggest a spin-glass ground state. An applied field of 7 T drives the insulator ground state to a ferromagnetic metallic state below T-C= 120 K. For a range of intermediate fields, the compound undergoes insulator-metal-insulator transitions which resemble those of 1:1 Mn3+/Mn4+ charge-ordered compounds. A temperature-field phase diagram is established which depicts different magnetic and electronic states.
