Abstract
As there are recent tendencies to raise horizontal frequencies so as to improve screen definition for high-quality TV and high definition display, ferrite core for deflective yokes requires materials with low coreloss in the areas of high frequencies. The researcher added CuO to low-loss Mg-Zn ferrite. After choosing MgO, ZnO, Fe$_2O_3$ and CuO, the researcher changed a ratio of composition, substituting MgO for CuO. These samples were sintered for three hours up to 980$^{\circ}C$~1350$^{\circ}C$. Measure magnetic permeability, electric loss, core loss and a rate of contraction.
