II-VI GROUP OR III-V GROUP BASED SINGLE CRYSTAL FERROMAGNETIC COMPOUND AND METHOD FOR ADJUSTING ITS FERROMAGNETIC CHARACTERISTICS

摘要

A II-VI Group or III-V Group based single crystal ferromagnetic compound, wherein a II or III Group element is substituted with at least one transition metal selected from the group consisting of V and Cr in the cases of a II-VI Group based compound selected from the group consisting of ZnTe, ZnSe, ZnS, CdTe, CdSe and CdS and a III-V Group based compound selected from the group consisting of GaAs, InAs, InP and GaP, or is substituted with at least one transition metal selected from the group consisting of V, Cr and Mn in the case of a III-V Group based compound selected from the group consisting of GaN, AlN, InN and BN; and a method for adjusting the ferromagnetic characteristics and/or the ferromagnetism transition temperature of the ferromagnetic compound, which comprises adding another transition metal element, an n-type dopant or a p-type dopant. The II-VI Group or III-V Group based single crystal ferromagnetic compound can transmit a light and also exhibits a high ferromagnetism transition temperature.
