The angular dependence of the exchange bias under the plain-domain-wall model

Exchange coupling between a ferromagnet (FM) and an antiferromagnet (AFM) has been extensively studied duo to its key role in applications such as giant magnetoresistive heads for high density recording systems, nonvolatile memory, and sensors. The angular dependence of exchange bias (ADEB) is an important aspect of the exchange bias effect, which is very informative to understand the origin of the interfacial exchange coupling. Additionally, the types, strength and orientation of the anisotropies in exchange-biased systems can also be detected by fitting the experimental measurements of ADEB with theoretically calculated ones [1].
