Since the wall thickness is at least 102 electron wavelengths, a domain wall acts, through the s-d exchange interaction, like a very weak and smooth potential barrier of height โ10โ2 eV, which does not reflect conduction electrons appreciably. The potential energy arises from the 4s conduction elect
