Abstract
The magnetic properties of Mn-Zn ferrite such as initial permeability, satu ration magnetization, Curie temperature, resistivity and power loss are aff ected greatly by the Fe2+ content in the raw materials. The experimental re sults show that low resistivity (rho) and high eddy current loss (P-e) are induced by the superfluous Fe2+ content in the raw materials; the scant Fe2 + content in the raw materials will increase hysteresis loss (P-h) and decr ease Curie temperature (T-c), saturation magnetization (M-s) and initial pe rmeability (mu (i)).
