摘要

This article deals with novel opto-magnetic and magneto-optical phenomena. These phenomena are demonstrated with metal polycyanides, which are classified as molecule-based magnets. CObalt hexacyanoferrate and copper octacyanomolybdate solids exhibit a photo-reversible enhancement of magnetization. These photo-magnetic phenomena are based on the photo-induced electron transfer between diamagnetic (or paramagnetic) state and their valence isomers exhibiting ferrimagnetism (or ferromagnetism). By a combination of photo-magnetism and mixed ferro-ferrimagnetism, a novel photo-induced magnetic pole inversion is demonstrated with an iron-manganese hexyacyanochromate. Each of these photo-magnetic phenomenon is the first known example in the whole field of magnetically ordered materials. Furthermore, Faraday spectra of molecule-based magnets were observed for the first time with electrochemically synthesized vanadium hexacyanochromate films. This Faraday effect originates from the intervalence charge-transfer band between vanadium and chromium ions in the visible region.
