Abstract
A formula for the rotational hysteresis parameter RH is found for the case of domain wall motion (Kondorsky model) in the presence of specimen demagnetizing fields. The particular case studied is thin magnetic films with infinite lateral extent. The result is that specimen demagnetizing reduces values of RH . The relation for RH is:
where x = 4πMs /Hc . The shape of the rotational torque curves is sketched.
where x = 4πMKeywords
