After suitable doping of Al,Si into MnBi, the doped film possesses hexagonal crystal structure with NiAs type and perpendicular anisotropy. Its maximum intrinsic Kerr rotation θKapproaches 2.04°. The observation of TEM shows that the crystalline size of this film is about 0.04 μm on a average. Meantime, it has good thermal stability. As a result, it is a promising material for the magneto-optical disc use. Moreover, the reason for the huge enhancement of the Kerr effect is discussed in this paper. © 1990.
