我们尝试设计通过光刺激表现出磁极（N 和 S）反转的磁体。 Fe1.5IICrIII(CN)6⋅7.5H2O 的磁化强度在可见光作用下以光子模式发生变化。铁磁体（Fe0.40IIMn0.60II）1.5CrIII（CN）6⋅7.5H2O由铁磁体（Fe-Cr系统显示光刺激引起的磁化强度变化）位点和亚铁磁体（Mn-Cr系统显示无光学响应）位点混合，在低于补偿温度（Tcomp = 19 K）的温度下表现出负磁化。在这种混合金属氰化物磁体中，我们成功地展示了一种新颖的磁行为“光致磁极反转”。此外，磁极反转可以通过交替的光和热刺激重复引起。
We tried to design the magnet exhibiting magnetic pole (N and S) inversion by photostimuli. The magnetization of Fe1.5IICrIII(CN)6⋅7.5H2O was changed in a photon mode by visible light. A ferro-ferrimagnet (Fe0.40IIMn0.60II)1.5CrIII(CN)6⋅7.5H2O mixed by ferromagnetic (Fe–Cr system showing the change of magnetization by optical stimuli) site and ferrimagnetic (Mn–Cr system showing no optical response) site showed negative magnetization at the temperature lower than compensation temperature (Tcomp=19 K). In this mixed metal cyanide magnet we have succeeded in demonstrating a novel magnetic behavior “photoinduced magnetic pole inversion.” Moreover, the magnetic pole inversion can be induced repeatedly by alternate optical and thermal stimulations.
