Multiscale simulations toward magnetic loss and magnetic recording

Magnetic simulations for magnetic material have attracted much attention for industrial and scientific purposes by utilizing the current computational power. In this context, the multiscale simulation technique is one of the most important methods to realize the human scale (time and length) simulations while maintaining the accuracy of electronic-level calculations. We have developed a multiscale simulation platform that can tackle several important magnetic properties, such as magnetic loss and magnetic recording, with solid bridges between the methodologies [1,2]. In this study, we consider some well-known materials and compare them with experiments to demonstrate the accuracy of our methodology. Multiscale simulation is a helpful tool for searching and optimizing high-performance magnetic materials at a macro scale.
