摘要： 在磁性材料中实现高效的自旋极化，是量子信息技术的应用基础。基于玻尔兹曼分布原理的普适性方案极化效率较低且条件要求苛刻，限制了实际应用。在部分体系的光化学和光物理过程中，电子的跃迁行为表现出自旋选择性，辅以光泵浦技术，可以在较宽松的实验条件下实现更高效率的自旋极化。本文结合近年研究的实际情况，介绍了两类光致自旋极化机制及其代表性磁性分子体系。

Abstract: Achieving high-efficiency spin polarization in magnetic materials is fundamental to quantum information technology. Conventional methods based on the Boltzmann distribution principle have low polarization efficiency and require harsh experimental conditions. This limits their practical application. However, certain systems exhibit spin-selective electron transitions during photochemical and photophysical processes. When combined with optical pumping techniques, these light-driven approaches enable highly efficient spin polarization under relatively mild conditions. This article introduces two types of light-induced spin polarization mechanisms and their representative magnetic molecular systems based on recent research progress.
