论文摘要
在这项工作中，我们提出了一个替代模型，以解释在自旋玻璃（SG）样系统中观察到的自发交换偏差（SEB）效应。与先前提出的模型一样（参考文献1），它基于磁性磁滞周期中类似SG样矩的非常规动力学。但是，使用对周期中放松的SG旋转量的可靠估计，新模型可以正确描述在不同温度和不同最大施加的磁场下进行测量的SEB的变化。
In this work we propose an alternative model to explain the spontaneous exchange bias (SEB) effect observed in spin glass (SG)-like systems. As in a previously proposed model (Ref. 1), it is based on the unconventional dynamics of the SG-like moments at the magnetic hysteresis cycle. However, using a reliable estimate of the amount of SG-spins that are relaxing during the cycle, the new model can correctly describe the changes in the SEB observed for measurements performed at different temperatures and different maximum applied fields.
