Heat generation materials under high frequency magnetic field were composed from manganese-zinc ferrite of magnetic semiconductor, cerium doped barium titanate (CBT) of PTC semiconductor and glass of low softening temperature. Their electric, magnetic and heat generation properties were investigated. The eddy current loss of the ferrite was found to mainly participate in the heat generation under high frequency magnetic field. The composite materials showed the heat generation in accordance with the content of ferrite. However, the composite could not be extended in controlling the eddy current of the ferrite
