Barkhausen noise from formation of 360^{∘} domain walls in disordered permalloy thin films

Barkhausen noise in disordered ferromagnets is typically understood to originate primarily from jerky field-driven motion of domain walls. We study the magnetization reversal process in disordered permalloy thin films using micromagnetic simulations and find that the magnetization reversal process c...
