Adjustment method of transparent ferromagnetic chemical compound and its ferromagnetic quality which the element which magnetic impurity such as transition metal or rare earths metal is not included, has the imperfect shell the solid solution are done

摘要

Being the chemical compound which is chosen from the group of the alkaline earths calcogen compound, the alkaline calcogen compound, I-VII family chemical compound, II-VI family chemical compound, III-V family chemical compound, IV-VI₂ family chemical compound, IV-IV family chemical compound and II-VII₂ family chemical compound, while B, C, by the fact that the solid solution it does the element of 1 where it has the imperfect p electron shell in the outermost shell of N, O, F, Si and Ge etc kinds at least, transmitting the light which features that ferromagnetic transition temperature is above room temperature, the transparent ferromagnetic chemical compound of the monocrystal which possesses high ferromagnetic quality. Valence electron control is done and with the adjustment, the accepter of density of the element which has the imperfect p electron shell in these outermost shells and the addition etc of the donor the ferromagnetic quality is adjusted.
