Micromagnetics and Spintronics: Models & Numerical Methods

Abstract

Micromagnetics and spintronics are crucial fields of study in the development of advanced materials for next-generation electronic devices. Micromagnetics focuses on the behavior of magnetic materials at micrometer scales,incorporating effects such as domain formation, magnetization dynamics, and the interactions between spins in different materials. Spintronics, on the other hand, explores the manipulation of electron spins in addition to charge, leading to novel applications in non-volatile memory devices and quantum computing. This paper presents an overview of the key models used in micromagnetics and spintronics, with a focus on the numerical methods for simulating these phenomena. The challenges associated with computational modeling and the potential for emerging techniques such as machine learning in improving simulations are also discussed. This article provides a comprehensive framework for understanding these fields and suggests future research directions to enhance the performance of spintronic devices
