有機磁性体
The magnet is used for a lot of electrical instruments including the computer now.  However, the recent electrical equipments and computers have been developed as a miniaturized and lightening in order to bring very easy and higher mobility as a ubiquitous lifestyle.  However, the limit has been caused in the miniaturization of the size in the magnet based on the inorganic substance such as iron and the cobalt that have been used up to now as an external storage device.  There is a big problem of the very expensive of the inorganic materials such as rare metal and a rare earth metal by a shortening of the metal all over the world.  Therefore the research of creating of novel organic compounds-based magnet should be required as a substituent of the metal-based magnets.  Up to now, the inter spin interactive can not be controlled freely in the organic-based magnets, and the concept to predict of the ferro-antiferro-magnetic interactive between the spins must required.  This study we investigate the electronic structure by DV-Xα method orbital calculation and a three dimensioal wave function discuss the spin-spin interaction of the synthesized organic-based magnets.
