Abstract
M-type hexagonal ferrites whose prototype chemical formula (BaFe.sub.12 O.sub.19) contains no zinc and W-type hexagonal ferrites whose prototype chemical formula is (BaZn.sub.2 Fe.sub.16 O.sub.27) can be successfully grown by LPE on spinel substrates having appropriate lattice parameters when controlled quantities of the zinc are present in the melts from which these hexagonal ferrites are grown. Using this growth technique, composites comprising a monocrystalline magnetic M-type or W-type hexagonal ferrite film on a non-magnetic single crystalline spinel substrate are provided.
