The invention belongs to the field of ferrite materials, and particularly relates to MnZn ferrite with curie point temperature sensitivity. The MnZn ferrite is prepared from the following components in parts by weight: manganese oxide, zinc oxide, molybdenum disulfide powder, nanometer titania, polyethylene glycol, graphene, white carbon black, carbonyl iron powder, cobaltous oxide, cobalt sesquioxide and the like. A sinter mixture is built by cooperation of materials with large superficial area ratio and small particle diameters and the materials containing water molecule structures and multiple ball-milling; the mixture can reach microscopic uniformity; the internal oxidative activity during sintering is high; the heat propagation is uniform; formation of uniform and fine manganese-zinc ferrite with small internal holes, high volume density and high grain purity can be promoted; meanwhile, the added white carbon black is high in migration rate and has good carrier conductivity; the temperature sensitivity of the manganese-zinc ferrite can be improved; and a new application of the manganese-zinc ferrite is increased.
