  • Photo-inducible magnetic exchange coupling device
    Patent number: 5723978
    Abstract: A magnetic device, comprises a first magnetic layer; a second magnetic layer on the magnetic layer and having a coercive force smaller than that of the first magnetic layer; a semiconductor layer between the first and second magnetic layers so that photo-induced magnetism occurs between the first and second magnetic layers when the semiconductor layer is irradiated with light, a third magnetic layer on the second magnetic layer, the third magnetic layer having a coercive force larger than the coercive force of the second magnetic layer, and a second semiconductor layer between the second and third magnetic layers, magnetism being induced between the second and third magnetic layers when the second semiconductor layer is irradiated with light.
