✦ Synopsis

We present wavelength dependence of photo-carrier-induced magnetization for (In,Mn)As=GaSb heterostructures, and discuss the problem involved in hole transfer from GaSb to (In,Mn)As across the (In,Mn)As=GaSb heterointerface. The reduction in coercive force by the light illumination has also been shown as a new e ect associated with carrier-induced magnetism.
