Outline of Final Research Achievements |
Magnetization reversal of nanomagnet has been studied by using magnetic tunnel junction with junction diameter of about 20 nm. In particular, the relationship between the magnetization reversal and device-processing conditions was studied. It was revealed that magnetization reversal of the nanomagnet changes depending on the device-processing conditions. It was also revealed that the change in the magnetization reversal can be explained by introducing reduction of magnetic anisotropy at the vicinity of the device edge by using micromagnetic simulation.
