Irradiating ${\rm Cu}_2{\rm Mo}({\rm CN})_8\cdot 8{\rm H}_2{\rm O}$ with blue light induces a global magnetization, whereas succeeding irradiations with red or longer-wavelength light demagnetize this material. We solve the time-dependent Schrodinger equation for an extended Hubbard model to reproduce the photoreversible magnetism. Monitoring the photoinduced optical-conductivity and angle-resolved-photoemission spectra, we reveal that the magnetic round trip by way of ferromagnetism is far from a return in terms of electronics. While visible-light-induced magnetization has never been observed in the tungsten analog ${\rm Cu}_2{\rm W}({\rm CN})_8\cdot 5{\rm H}_2{\rm O}$, infrared-light irradiation may magnetize this material as well.

方形反棱柱八氰金属酸盐中单向电子的光致双向磁性

用蓝光照射 ${\rm Cu}_2{\rm Mo}({\rm CN})_8\cdot 8{\rm H}_2{\rm O}$ 会引起全局磁化，而随后用红色或较长波长的光会使这种材料退磁。我们为扩展的哈伯德模型求解与时间相关的薛定谔方程，以重现光可逆磁性。监测光致光电导率和角分辨光发射光谱，我们发现通过铁磁性的磁性往返远非电子学方面的回报。虽然在钨模拟物中从未观察到可见光诱导的磁化 ${\rm Cu}_2{\rm W}({\rm CN})_8\cdot 5{\rm H}_2{\rm O}$ ，红外光照射也可以磁化这种材料。
