abstract = "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.",

note = "Funding Information: In conclusion, the presence of magnetically damaged (dead) layers in lapped surfaces of Mn-Zn and Ni-Zn ferrites have been demonstrated by measuring the magnetostrictive re- sponse. Using a simple model, the thickness of the dead layers has been estimated from the measurements. Furthermore these layers are shown to be a consequence of the deformation and residual stresses induced by lapping. In general lapping is found to introduce a thicker dead layer in Ni-Zn ferrite compared to Mn-Zn ferrite which is probably due to the larger magnetostriction of Ni-Zn ferrite.
