In the current holographicspatial light modulators that enable ideal 3D image display with driving method of "spin-transfer magnetization reversal", since a current must be passed through each pixel, power consumption become huge to achieve high resolution, large screens, and wide viewing areas. Another problem is that the brightness is not so high due to the insufficient magnetic Kerr effect of the spatial light modulator. Here, we previously verified "magnetization reversal by electric field application" in multiferroic thin films. Furthermore, we also proposed "magnetization transfer by electric field application" in a laminated film of multiferroic thin film and ferromagnetic metal thin film, in which the magnetization of the ferromagnetic metal thin film is reversed by magnetic interaction through the magnetization reversal of the multiferroic thin film by electric field application to the laminated film, and we have also successfully verified its operation. In this study, we have newly proposed "magnetization transfer Kerr amplification by electric field application" in a laminated film of multiferroic thin film and ferromagnetic metal thin film, which is a further development of the magnetization transfer by electric field application. By giving the multiferroic thin films a cavity function in addition to the magnetization transfer function, and giving the ferromagnetic metal thin film a half mirror function in addition to the magnetic Kerr effect derivation function, it becomes possible to control the magnetic Kerr effect and its amplify by electric field application. To verify this functionality, we are fabricating multiferroic thin films with large saturation magnetization and perpendicular magnetic anisotropy, fabricating metal ferromagnetic thin films with large magnetic Kerr rotation angle and perpendicular magnetic anisotropy but low coercivity, and fabricating laminated films with the multiferroic thin film and metal ferromagnetic thin film. |
