Spin-glass state and magnetic-field-induced phenomena in distorted Eu{sub 0.58}Sr{sub 0.42}MnO{sub 3} perovskite
- Laboratoire CRISMAT, ISMRA, 6 Boulevard du Marechal Juin, 14050 Caen Cedex (France)
Magnetic and magnetoresistance measurements were carried out on a distorted perovskite, Eu{sub 0.58}Sr{sub 0.42}MnO{sub 3}. In the absence of applied magnetic field, this compound is an insulator down to 5 K. Results of the ac- and dc-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{sub C}=120 K. For a range of intermediate fields, the compound undergoes insulator-metal-insulator transitions which resemble those of 1:1 Mn{sup 3+}/Mn{sup 4+} charge-ordered compounds. A temperature-field phase diagram is established which depicts different magnetic and electronic states. {copyright} {ital 1997} {ital The American Physical Society}
