Research Abstract |
We have investigated the magnetic properties of quaternary mixed crystals in which two kinds of transition-metal elements are incorporated in II-VI compounds, with an aim to clarify the interaction between different kinds of transition-metal elements and to seek the possibility of novel magnetism. In the case of (Cd,Mn,Cr)Te, it is found that the interaction between Mn, which is antiferromagnetic in the ternary compound (Cd,Mn)Te, turns to ferromagnetic by the incorporation of a small amount of Cr. This result indicates that the ferromagnetism is enhanced by incorporating Mn and Cr simultaneously in the crystals. On the other hand, in the case of (Zn,Cr,Fe)Te, it is found that the saturation magnetization decreases and the coercive force increases with the increase of the Fe composition at a constant Cr composition, which suggests the antiferromagnetic interaction between Cr and Fe.
