Abstract

High density Mn-Zr ferrites have been extensively used in recording head applications. The properties like permeability, los~, etc., depend on the preparation method. The :roperfies play major role in selecting these materials for various applications.In this present work., we have prepared Mn-Zn ferrites musing metal hydrazine carboxylate precursors (N2Hs)3Mn0.sZn0.sFe2(N2H3COO)33H20. The precursor decomposes at very low temperature (~250°C) to form ultrafine Mno.sZn0.sFe204. The partic~,e size permeability spectrum, microstructure and magnetic properties will be discussed in this paper.
