Exchange bias without directional anisotropy in Permalloy/CoO bilayers
Alexander Mitrofanov, Guanxiong Chen, Alexander Kozhanov +1
We utilize transverse ac susceptibility measurements to characterize magnetic anisotropy in archetypal exchange-bias bilayers of ferromagnet Permalloy (Py) and antiferromagnet CoO.…

Experimental demonstration and analysis of random field effects in ferromagnet/antiferromagnet bilayers
Guanxiong Chen, Dylan Collette, Sergei Urazhdin
More than 30 years ago, Malozemoff (Phys. Rev. B 35, 3679 (1987)) hypothesized that exchange interaction at the interface between a ferromagnet (F) and an antiferromagnet (AF) can…
