Abstract

We found out that the addition of various rare earth metal oxides (Ce2O3,Pr2O3,Eu2O3,Dy2O3, Ho2O3,Er2O3,Yb2O3) have improved both the saturation magnetization(Es) and the relative permeability (Er) of Mn-Zn ferrite single crystals. Fspecialy, the Ds shows the maximum value of 10.56-10-3Wbkg-1 when 0.05mol% Er203 is added to Mn0.54Zn0.35Fe2.10O4.It is considered that the effect of the Er2O3 addition on magnetic properties is closely related to the dissolution of Er into the Mn-Zn ferrite. The Mn-Zn ferrite containing Er2O3 is expected to be used as magnetic head mmaterials.
