The Hysteresis LOOP Studies Of Magnetic TunnelJunction-basedMolecular Spintronics Devices (mtjmsd) Employing Monte Carlo Simulations

Abstract

The hysteresis loop investigations of different size magnetic tunnel junction molecular spintronics devices (MTJMSD) have been done by Monte Carlo simulation (MCS). We employed a continuous MCS algorithm to investigate single-molecule magnet SMM's spin state's impact as a function of molecular exchange coupling strength. The applied magnetic fields were ramped at a variety of ranges of increments, unfolding physics behind the magnetization nature of each MTJMSD. The magnetic moment changes with applied magnetic fields exhibit the characteristics of devices being studied. The MTJMSDs were studied for ferromagnetic and antiferromagnetic exchange couplings. The magnetic moment saturation, retentivity, coercivity, and permeability are studied.
