Phys. Rev. B 58, R14717 - R14720 (1998)Exchange coupling and macroscopic domain structure in a wedged permalloy/FeMn bilayer
S. M. Zhou, Kai Liu, and C. L. Chien
Local Kerr effect and magnetometry measurements reveal that switching in exchange-coupled wedged-permalloy/FeMn bilayers involves only two macroscopic domains, extending across the entire sample, separated by a 180° domain wall, which moves along the wedge direction. The squareness of the hysteresis loop of such exchange-coupled layers depends on the thickness variation of the sample under measurement. ©1998 The American Physical Society
