摘要

我们发现了一个巨大的交换偏置(EB)在低温下的巨大磁阻Nd2/3Ca1/3MnO3锰矿，其固有的界面交换耦合明显。这一现象证实了我们之前的假设，即化合物的低温磁性结构是由浸入电荷有序反铁磁矩阵中的小(纳米级)铁磁团簇表示的。Nd2/3Ca1/3MnO3钙钛矿在低温下的磁性行为与自组织相分离形成的团簇玻璃磁性状态一致。实验还揭示了零场冷却磁化的慢弛豫现象。它证实了化合物的团簇玻璃磁性态。

Giant exchange bias in nano phase-segregated Nd2/3Ca1/3MnO3

We have revealed a giant exchange bias (EB) in a colossal magnetoresistance Nd2/3Ca1/3MnO3 manganite at low temperatures, evident of its intrinsic interface exchange coupling. The phenomenon found confirms our previous assumption that the low temperature magnetic structure of the compound is represented by small (nano-sized) ferromagnetic clusters immersed within the charge-ordered antiferromagnetic matrix. Magnetic behavior of the Nd2/3Ca1/3MnO3 perovskite at low temperature is consistent with its cluster-glass magnetic state originating from the self-organized phase separation. Slow relaxation of zero-field-cooled magnetization has been experimentally revealed as well. It confirms the cluster glass magnetic state of the compound.
