Title: Multilayer iron nitride hard magnetic materials

Abstract

The disclosure describes multilayer hard magnetic materials including at least one layer including α″-Fe16N2 and at least one layer including α″-Fe16(NxZ1-x)2 or a mixture of α″-Fe16N2 and α″-Fe16Z2, where Z includes at least one of C, B, or O, and x is a number greater than zero and less than one. The disclosure also describes techniques for forming multilayer hard magnetic materials including at least one layer including α″-Fe16N2 and at least one layer including α″-Fe16(NxZ1-x)2 or a mixture of α″-Fe16N2 and α″-Fe16Z2 using chemical vapor deposition or liquid phase epitaxy.
