Magnetic Anisotropy in Ordered and Disordered CoPd Alloys: A First-Principles Study — •Christian Maas, Michael Czerner, and Christian Heiliger — Institute for Theoretical Physics, Justus Liebig University Giessen

Understanding the magnetic anisotropy in magnetic materials is crucial for designing devices like sensors or data storage. In this work, we present ab initio density functional theory calculations of the magnetocrystalline anisotropy of Co_xPd_(1−x) alloys with varying concentrations as well as L1₀ like [CoPd]_x[PdCo]_(1−x) structures. We also show results for ordered layer structures with different thicknesses of Co and Pd layers. For our calculations, we employ the relativistic screened Korringa-Kohn-Rostoker Green’s function method. The alloys are treated within the coherent potential approximation. Additionally, we explore the magnetic anisotropy of thin Co_xPd_(1−x) films, considering both the magnetocrystalline and shape anisotropy.
