Abstract

MgCuZn ferrites were fabricated by the traditional oxide-sintering method to explore the way to improve their sintering characteristics and soft magnetic properties. Effect of Bi and Mo co-doping on magnetic performances of MgCuZn ferrites with lower sintering temperature and high initial permeability was discussed. Results show that the density is larger than 4.75g/cm3 for the MgCoZn ferrite sintered at 1020℃with moderate quantity of Bi and Mo doping(0.6wt% and 0.1wt%, respectively), initial permeability is as large as 1240 and quality factor is as high as 33.8 at 100kHz, respectively. Thus, MgCuZn ferrite may be used in multilayer chip inductor by appropriate constituents, doping and preparing technology.
