Research Abstract |
The purpose of this research project is to realize a microwave-assisted magnetization reversal in perpendicularly magnetized films with a large magnetic anisotropy. The results are summarized as follows : (1) The geometrical design of coplanar waveguide producing a microwave field was optimized to be able to realize the microwave-assisted magnetization reversal. (2) It was experimentally confirmed that the magnetization reversal of Co/Pd multilayer with a perpendicular magnetic anisotropy was encouraged by the application of microwave field with a frequency of 10% lower than the intrinsic ferromagnetic resonance frequency.
