The structure of a field effect transistor (FET) was used for isothermal and reversible electric-field control of the ferromagnetism of (In,Mn)As magnetic semiconductors. The ferromagnetic transition temperature was controlled isothermally and reversibly by varying the gate electric field. The field-controlled ferromagnetism was expected to be used in the integration of ferromagnetic devices with nonmagnetic devices such as lasers and transistors in use in electronics.
