| 摘 要： | 霍尔天平材料中层间耦合作用易于调控,基于此可以实现多组态磁存储模式,其区别于当前基于自旋阀或者磁性隧道结的传统二组态磁存储原理.与此同时,还可以在存储单元中实现信息的逻辑运算从而提高器件整体的运算效率.这一设计有利于自旋电子学器件的微型化、集成化,有望从物理原理上解决当前基于自旋阀或者磁性隧道结的传统二组态自旋电子学材...

| Abstract: | To break through the conventional binary storage based on spin valves and magnetic tunnel junctions,multi-state storage has been successfully achieved in Hall balance.Meanwhile,logic operation can be realized in the storage cell of Hall balance to improve the operation efficiency.Therefore,the concept of Hall balance will benefit the device integration,which provides an effective insight into fabricating the development of spintronics.In this topical review article,firstly the background of memory based on Hall balance is introduced.Secondly,the concept and recent progress of Hall balance are briefly summarized.Thirdly,the manipulation of anomalous Hall resistance ratio(HRR)and its physical mechanism is systematically investigated.Furthermore,magnetic skyrmions and their dynamics in Hall balance are presented in detail.Finally,the application of Hall balance to other kinds of materials is discussed and prospects its future. |
