| 中文摘要 | We observed an exchange bias effect in La0.5Ca0.5FeO3-delta perovskite compound. The exchange bias is associated with the charge disproportionation transition from Fe4+ ions to Fe3+ and Fe5+ ions below 175 K. The competition between the ferromagnetic interaction of Fe3+ and Fe5+ ions and the antiferromagnetic one of Fe3+ and Fe3+ ions results in a unidirectional anisotropy in the cluster-glass system. An antiferromagnetically interfacial exchange coupling constant J (i)a parts per thousand a'1.95 meV at the cluster-glass region was yielded by fitting the cooling field-dependence of the exchange bias field. |
