SINGLE CRYSTAL HEXAGONAL FERRITES.

Abstract

Single crystals of ZnY and ZnY with additions of MnO2 have been grown from barium borate melts. Chemical composition, saturation magnetization, lattice parameter, and resonance linewidth were measured on single and polycrystalline samples of these materials. Substitution of manganese materially improves the resonance linewidth of ZnY. Typical linewidth values at 9.2 Gc for spheres of pure ZnY were 50 Oe, whereas corresponding values on ZnY crystals containing manganese, produced under identical conditions, were of the order of 10 Oe.
