Abstract

We have theoretically investigated the wave packet dynamics method for the write characteristics of the nanoscale magnetic tunnel junction with synthetic ferrimagnets based on the microscopic quantum electron model. In this study, we have performed numerical simulation of two bands tight binding electron model. In order to take into account the electron-electron correlation, we consider the on-site Coulomb interaction, Hund exchange coupling and finite electric field. In our simulation, we employ the time dependent molecular field approximation. Based on the simulation using wave packets, we have clarified the role of ferrimagnet in the nanoscale magnetic tunnel junction.
