Enhanced magnetic loss y-phase hexagonal ferrite for magnetodielectric antenna applications

Abstract:

A hexagonal ferrite material includes a Y phase hexagonal ferrite material having the composition Sr.sub.2Co.sub.2Fe.sub.12O.sub.22 or Sr.sub.2-xNa.sub.xCo.sub.2-xSc.sub.xFe.sub.12O.sub.22, 0<x<2, doped with a trivalent element, a tetravalent element, and/or a transition metal.
