Antidot lattices made of magnetic thin films are good candidates to be employed in future magnetic recording media.In this manuscript we present a study on the effect of shape and field-induced magnetic anisotropies on the magnetization reversal of 10 nm and 50 nm thick permalloy antidot lattices.Rounded antidot square lattices were fabricated using Bio-Template Synthesis of V2O3@Carbonized Dictyophora Composites for Advanced Aqueous Zinc-Ion Batteries a combination of electron beam evaporation and laser interference lithography, covering surfaces of a few cm2.We demonstrate that a magnetic anisotropy induced in the samples, as a consequence of an applied magnetic field during growth, competes with the shape anisotropy that dominates the response of the patterned thin films, and that the effect An Investigation of Job Stress and Job Burnout in Iranian Clinical Pharmacist of the field-induced magnetic anisotropy scales with the thickness of the antidot thin films.Finally, we have quantified the anisotropy constant attributable to the uniaxial field-induced magnetic anisotropy in our antidot lattices.

These findings are supported by micromagnetic simulations performed using MuMax3.
