摘　　要：磁性材料中自旋亚稳态的存在往往会使体系中出现新奇的物理现象,例如磁跳变、变磁相变、斯格明子等.本文从亚稳态和自发交换偏置的研究现状出发,介绍了基于自旋亚稳态设计、构建自发交换偏置新体系的思路和研究方法,力图以此激发学生的创新思维,同时为相关领域的科研人员提供借鉴.The existence of spin metastable states in magnetic materials often causes novel physical phenomena in the system,such as magnetic jumps,magnetic phase transitions,skyrmions,etc.Starting from the respective research status of metastable state and zero-field-cooling exchange bias,the ideas and research methods of constructing a new system for zero-field-cooling exchange bias were introduced based on spin metastable design.The students’innovative thinking were stimulated and the reference for researchers were provided in related fields.
