Description

In this work we present a study of static and dynamic properties of two-dimensional arrays of permalloy (Py) Ni80Fe20 ellipsoidal nanomagnets. The samples were studied by dc-magnetization and reversible susceptibility measurements. The magnetization loops at room temperature showed wasp-waisted shapes that can be correlated with the magnetic shape anisotropy contribution of these samples. The critical curves were measured by the method of reversible susceptibility, where the angular variation was conducted with magnetic field in plane.
