The Influence of Anisotropy on the Magnetic Properties of Materials

Abstract

Magnetic anisotropy plays a pivotal role in determining the magnetic behavior of materials, influencing their macroscopic properties, such as magnetization, coercivity, and magnetic susceptibility. This phenomenon arises due to the directional dependence of magnetic properties, which is determined by crystal symmetry, shape, and magnetoelastic effects. This paper explores the origins, mechanisms, and consequences of magnetic anisotropy in various materials, with a particular focus on its impact on the design and performance of magnetic devices, such as storage systems and spintronic applications. We also discuss the experimental techniques used to investigate anisotropy, including magnetometry and electron microscopy.
