Numerical study of magnetic properties for Co-Fe-Nb nanofilms as promising materials for magnetoresistive memory

The paper presents an overview of the magnetic resistive memory varieties, discusses their design features, weaknesses and benefits, and provides a comparative characteristic. A review of a combined mathematical model that jointly describes the change of spins and coordinates of atoms (spin-lattice dynamics) is given. In general, the model can use any form of interatomic force potential and describes various contributions to the magnetic Hamiltonian. In this work, a simplified form of the magnetic Hamiltonian, taking into account only the Zeeman and exchange interactions, was considered to investigate magnetic interactions. The described model is implemented in the SPIN software package in the freely distributed LAMMPS complex. In this work, computational experiments were performed using the MEAM potential.
