在反钙钛矿化合物Ga1-xNMn3 +x （x = 0.06和0.1）中观察到零场冷却（ZFC）交换偏置（EB）。在自旋玻璃（SG）基体中证明了铁磁团簇的存在。认为ZFC‐EB是由沿FM/SG界面等温形成的单向各向异性引起的。对于这种典型的物理体系，初始磁化过程和FC过程两种方式都可能导致材料的单向各向异性。此外，ZFC后的训练效果与传统FC - EB系统相似。
Zero‐field cooling (ZFC) exchange bias (EB) was observed in antiperovskite compounds Ga1–xNMn3+x (x = 0.06 and 0.1). The existence of ferromagnetic (FM) clusters has been demonstrated in a spin glass (SG) matrix. The ZFC‐EB is suggested to originate from the unidirectional anisotropy formed isothermally along the FM/SG interface. For this typical physical system, both ways including the initial magnetization process and FC process could result in the unidirectional anisotropy. In addition, the training effect after ZFC is similar to those observed in conventional FC‐EB systems.
