Abstract

Vision of ferromagnet/semiconductor hybrid as a strongly coupled but flexible spin system is presented. We analyze the experiments and argue that contrary to the common sense the nonmagnetic semiconductor plays a crucial role in manipulating of ferromagnetism. The magnetism of the hybrid (magnetic hysteresis loop and the orientation of magnetization vector in space) is tuned both optically and electrically with the help of semiconductor. As a result the hybrid represents an elementary magnetic storage with electronic record and readout
