Abstract
Anisotropic magnetoresistance (AMR) effect has been discovered over one century, but keeps attracting people's special attention due to its wide applications in magnetic devices as well as its intimate relationship with the most fascinating physics such as spin–orbit interaction and spin–charge coupling. In this review article, we introduce the general characters and tuning methods of AMR effect in perovskite manganites, the typical strongly correlated electron system, and discuss the possible mechanisms behind. Outlooks of the AMR effects in manganites and related devices are also addressed.
