Magnetic behavior of amorphous CoP cylinder arrays

Abstract

Arrays of low-aspect-ratio cylindrical amorphous CoP nanomagnets with diameters near 100 nm have been fabricated using electrodeposition. The remanence of individual particles and the easy axis direction are consistent with the predictions of a micromagnetic model, but the behavior of the arrays is dominated by magnetostatic interactions because the switching fields of the particles are low compared to the magnitude of the nearest-neighbor interactions.
