Abstract

We report the experimental and theoretical characterization of the angular dependent magnetic field and microwave frequency response of isolated mesoscopic permalloy nanoellipses for geometries in which the static magnetic field is either parallel or perpendicular to the microwave magnetic field. We show how these spectra form a basis for interpreting the ferromagnetic resonance spectra of lattices based on such structures, including those containing frustrated regions, such as artificial spin ice structures.
