Micromagnetic simulations of hysteresis loops in ferromagnetic Reuleaux's triangles

We investigate the magnetic behavior of Fe, Co, Ni, and permalloy nanomagnets using micromagnetic simulations. We propose a Reuleaux's triangle geometry shape for the individual nanomagnets. Reuleaux's triangle combines the equilateral triangle and circular geometry. The effects of varying...

description We investigate the magnetic behavior of Fe, Co, Ni, and permalloy nanomagnets using micromagnetic simulations. We propose a Reuleaux's triangle geometry shape for the individual nanomagnets. Reuleaux's triangle combines the equilateral triangle and circular geometry. The effects of varying the thickness (10, 20, and 40 nm ) of these structures on the remanence magnetization and the coercive field are analyzed. Our results demonstrate that in most cases the hysteresis loops follow C, Ω , and vortex configurations in the magnetization reversal process. In addition, the magnetic properties of the small arrays of these nanomagnets are presented.
