Applications of Materials Modeling to Magnetism, Magnetic Materials, and Spintronics: Overview
Magnetism underpins many applications in modern technology, where either its static or dynamical properties are exploited. This chapter discusses some of these applications, in particular focussing on three main aspects. Firstly, it will review how modern electronic structure theory can contribute to the discovery and design of novel magnetic materials with multiple functionalities. Secondly, it will address the phenomena related to magnetization dynamics for both spintronics and data-storage applications. Finally, it will look at the interplay between electrical currents and spins. Throughout the chapter special attention will be devoted to present both the necessary theoretical background and discuss how theory may underpin the development of applications.
