Title: Applied magnetic field synthesis and processing of iron nitride magnetic materials

Abstract

A method may include annealing a material including iron and nitrogen in the presence of an applied magnetic field to form at least one Fe16N2 phase domain. The applied magnetic field may have a strength of at least about 0.2 Tesla (T).
