Abstract
Preparation of GaAs-Fe composite structures has been studied by molecular-b eam epitaxy. Enhanced magnetization has been observed under the red-light i rradiation at 160 K. Through the study of both magnetization and magnetotra nsport characteristics, we believe that enhanced magnetization is strongly related to the interaction between photogenerated carriers and magnetic inc lusions.
