An interesting evolution of spin glass behaviors and the corresponding exchange bias effects were observed by quenching Ni₅₀Mn₄₂In₃Sb₅ Heusler alloys at different temperatures. When the alloy is quenched at 1173K, it will freeze from antiferromagnetic to spin glass at low temperature under an external magnetic field, creating a giant exchange bias field up to 9063Oe through the pinning effect. In another case, the superparamagnetic in alloys quenched at 473K will transform to superspin glass after zero-field cooling at low temperatures instead. As a result, a spontaneous exchange bias effect up to 581Oe can be achieved.

通过热处理温度调节 Ni50Mn42In3Sb5 Heusler 合金的交换偏置效应

通过在不同温度下对Ni ₅₀ Mn ₄₂ In ₃ Sb ₅ Heusler 合金进行淬火，观察到自旋玻璃行为的有趣演变和相应的交换偏置效应。当合金在 1173K 淬火时，它会在外部磁场的作用下从反铁磁性冻结到低温旋转玻璃，通过钉扎效应产生高达 9063Oe 的巨大交换偏置场。在另一种情况下，在 473K 淬火的合金中的超顺磁性将在低温零场冷却后转变为超自旋玻璃。结果，可以实现高达 581Oe 的自发交换偏置效应。
