## Description

- description: The realization of spin manipulation using electric fields is anticipated
    to be a promising route toward future spintronic devices with ultra-low driving
    power as well as zero standby power, such as voltage-controlled (VC)—magnetoresistive
    random access memory (MRAM). Among various methods, the VC magnetic anisotropy
    (VCMA) effect in magnetic tunnel junctions (MTJs) is regarded as a particularly
    effective approach for achieving electric-field-induced magnetization control.
    One of the most important technical challenges in VC-MRAM development is to achieve
    a large VCMA coefficient, which is essential for ensuring scalability and reliable
    information writing. This review discusses the fundamental aspects of the VCMA
    effect and outlines recent attempts to optimize material and device structures
    to improve the VCMA coefficient in both epitaxial and polycrystalline MTJs.
