Abstract :
A simple physical model of the action of point defects on a domain wall bowing in the low field region is presented. A relationship between initial permeability and defect density is derived. Experimental results on the relation between initial permeability and carbon content in spheroidized iron carbon specimens are presented and the results are discussed in connection with this model
