Lecture

Magnetic anisotropy: fundamentals and applications

Description

This lecture covers the concept of magnetic anisotropy energy (MAE) in bulk and free magnetic atoms, the relationship between MAE and orbital moments, the limit of MAE in 3d metal atoms, and the thermal stability of bit magnetization. It also discusses the superparamagnetic limit, coherent magnetization reversal, and atomic-scale engineering of MAE in nanostructures.
