Effect of BiVO4 doping on the magnetic properties and microstructure of NiCuZn ferrites

摘要

Effects of BiVO4 addition on the microstructural development and magnetic properties of a NiCuZn ferrite were investigated by conventional solid state reaction method. For the low temperature sintering (< 961 A degrees C), 0-2 wt% of BiVO4 was added to the ferrites. The grain size and bulk density gradually increased with the increase in the BiVO4 content and more uniform and compact structure at 1.0 wt% BiVO4 were obtained. The permeability decreases gradually with increase in BiVO4 content BiVO4 doped in NiCuZn ferrites improved magnetic properties and reduced the magnetic loss tangent. The samples may be excellent candidates to fabricate multilayer chip inductors and LTCC passive devices.
