The thickness of surface damaged layers in lapped surfaces of ferrite ceramics has been estimated by measuring the magnetostrictive response. Both Mn-Zn and Ni-Zn ferrite surfaces are found to have damaged or dead layers extending from 5 to 100 micrometers into the surface. In general, Mn-Zn ferrite is found to have a shallower surface damaged layer compared to Ni-Zn ferrite which is most likely due to the smaller magnetostriction of Mn-Zn ferrite. The dead layers are shown to arise due to the deformation and residual stresses generated by the lapping process.
