摘要：
A model for domain wall motion in ferromagnets is analyzed. Long-range magnetic dipolar interactions are shown to give rise to self-similar dynamics when the external magnetic field is increased adiabatically. The power spectrum of the resultant Barkhausen noise is of the form 1/omega(alpha), where alpha approximate to 1.5 can be estimated from the critical exponents for interface depinning in random media.
