摘要
We present CMTJ—a simulation package for large-scale macrospin analysis of multilayer spintronics devices.Apart from conventional simulations,such as magnetoresistance and magnetisation hysteresis loops,CMTJ implements a mathematical model of dynamic experimental techniques commonly used for spintronics devices characterisation,for instance:spin diode ferromagnetic resonance,pulse-induced microwave magnetometry,or harmonic Hall voltage measurements.We find that macrospin simulations offer a satisfactory level of agreement,demonstrated by a variety of examples.As a unified simulation package,CMTJ aims to accelerate wide-range parameter search in the process of optimising spintronics devices.
