Abstract

An apparatus for, and a method of controlling magnetic anisotropy in a magnetic material comprises directing a layer of powdered metal material to a heat conducting substrate. Electromagnetic energy is applied to the powdered material sufficient to melt the powdered material which is subsequently cooled to create a solid layer on the substrate. An external magnetic field is applied to the material during at least the cooling step so as to imprint the solid magnetic material layer with magnetic anisotropy. Various novel magnetic structures can be fabricated using the technique.
