| Outline of Final Research Achievements |
New magnetization reversal methods can be realized by using the effect of magnetization dynamics, in which both magnetization and magnetic field are treated as time dependent terms. In this study, magnetization reversal experiments was carried out based on large angle precessional motion of magnetization produced by applying pulse field normal to the magnetization. Both experiments and calculation results showed that magnetization reversal field can be reduced down to 70 % of that in a static field by using pulse fields with rise time shorter than the relaxation time of magnetization.
