Accurately controlling magnetic and spin states presents a significant challenge in spintronics, especially as demands for higher data storage density and increased processing speeds grow. Approaches such as light control are gradually supplanting traditional magnetic field methods. Traditionally, the modulation of magnetism was predominantly achieved through polarized light with the help of ultrafast light technologies. With the growing demand for energy efficiency and multifunctionality in spintronic devices, integrating photovoltaic materials into magnetoelectric systems has introduced more physical effects. This development suggests that sunlight will play an increasingly pivotal role in manipulating spin orientation in the future. This review introduces and concludes the influence of various light types on magnetism, exploring mechanisms such as magneto-optical (MO) effects, light-induced magnetic phase transitions, and spin photovoltaic effects. This review briefly summarizes recent advancements in the light control of magnetism, especially sunlight, and their potential applications, providing an optimistic perspective on future research directions in this area.
在自旋电子学中，精确控制磁态和自旋态是一项重大挑战，尤其是随着对更高数据存储密度和更快处理速度的需求不断增长。诸如光控等方法正逐渐取代传统的磁场方法。传统上，磁性调制主要是借助超快光技术通过偏振光来实现的。随着自旋电子器件对能量效率和多功能性的需求不断增加，将光伏材料集成到磁电系统中引入了更多物理效应。这一发展表明，未来阳光在操纵自旋取向方面将发挥越来越关键的作用。本文综述介绍并总结了各种光类型对磁性的影响，探讨了磁光（MO）效应、光致磁相变和自旋光伏效应等机制。本文简要总结了磁性光控尤其是阳光光控方面的最新进展及其潜在应用，为该领域未来的研究方向提供了乐观的视角。
