Outline of Final Research Achievements

In order to develop spin-wave devices for detection of biological molecules using magnetic nano-particles, perpendicular magnetized films have been prepared and their spin dynamics were measured. Perpendicular magnetized Co/Ni multilayers with period of 1 nm exhibit large perpendicular anisotropy, where the multilayers with Pt underlayer show larger anisotropy compared to the films with Ta underlayer. In spin dynamics observation using pump-prove method, precession of magnetization caused by a pump light sustained during over 300 ps. Damping parameter obtained fitting method of Co/Ni multilayers were approximately 0.020. This value is less than half value of 0.046 for GdFeCo amorphous films. These results implies that Co/Ni multilayers were appropriate material for spin-wave devices.
