论文摘要
放射$ {\ rm cu} _2 {\ rm mo}({\ rm cn})_ 8 \ cdot 8 {\ rm h} _2 {\ rm h} _2 {\ rm o} $带有蓝光诱导全球磁性化,而诱导了一个全球磁化,而将其成功地发射到重新或更长的范围内,并启动了重新启动。我们为扩展的哈伯德模型求解时间依赖性的schrödinger方程来再现光学磁性。监测光诱导的光导率和角度分辨 - 发射光谱,我们揭示了通过铁磁性的磁性往返行程,远非电子的回报。虽然在钨模拟$ {\ rm cu} _2 {\ rm w}({\ rm cn})_ 8 \ cdot 5 {\ rm h} _2 _2 _2 _2 {\ rm o} $,infrigh-indize mays nize and ipe nize。
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 Schrödinger 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.
