Abstract :
Depending on the geometry and the magnetic material with its magneto crystalline anisotropy, magnetic nanostructures frequently display fascinating shape anisotropies that may provide novel potential applications. It is possible to investigate the impact of superposing shape anisotropies with various magneto crystalline anisotropies due to the roughly two-orders-of-magnitude difference in the anisotropy constants of the pure magnetic materials iron, cobalt, and nickel. In this article, we provide results from simulations of three distinct hexagonal-shaped nanomagnets made of iron, cobalt, and nickel that are angle-dependent. For nickel nanomagnets, the typical hysteresis loops, which are typically devoid of steps, are visible. However, cobalt produces a wide variety of magnetization reversal processes with several steps that change over the course of repeated simulations as a result of variations in the anisotropy axes in different grains of the nanoparticles. Iron provides the best co
