A reversible tuning and a persistent (irreversible) modification of physical properties by external stimuli are one of the main challenges in materials science. Recently, current-induced insulator-metal transition, electrochromism, photo-induced magnetization, magnetic-field induced structural phase transtion, electrochemical control of magnetization etc. have been reported. Especially, photo-control over the physical properties is important from the　viewpoint of the practical application as well as the basic science. The photo-tunable compounds can be used future memory devices, optical switches and so on.
