Spin-glass state in Y0.7Ca0.3MnO3

Journal Article


Abstract


  • Magnetisation and AC susceptibility were measured on perovskite Y0.7Ca0.3MnO3 at DC fields up to 5 T and AC field of 1 Oe with frequencies of 21, 217 and 2000 Hz. A large irreversibility was observed in the zero-field cooled and field-cooled magnetisation with a cusp at Tcusp in ZFC magnetisation. AC susceptibility also showed a cusp at the Tcusp which shifts to high temperature with increasing frequencies. This suggests a spin-glass state in Y0.7Ca0.3MnO3. The spin-glass state was totally suppressed at a high field of 5 T. © 1998 Elsevier Science B.V. All rights reserved.
