Abstract
We examined the reduction of the core loss of Mg-Mn-Zn ferrite for deflection yoke cores. We tried to decrease hysteresis loss by selection of composition and additive, because hysteresis loss is much larger then eddy current loss in Mg-Mn-Zn ferrite having high resistance. We succeeded in decreasing hysteresis loss and improved the core loss approximately 30% compared with conventional materials. And as the result of a simulation, we can expect that the rising temperature of it is smaller than that of our conventional materials for deflection yoke at high frequencies and high magnetic flux density.
