Perspective on anisotropic magnetoresistance


    Magnetoresistive phenomena span a large set of acronyms such as GMR, TMR, AMR, CMR and AHE, PHE     concerning the diagonal and off-diagonal resistivity tensor components, respectively (whereas it     should be noted that this list is by no means complete). In this talk, an overview of _only_ the     anisotropic magnetoresistance (AMR) will be given, in the context of all other mentioned acronyms,     and its one-and-half century long history commented on. Microscopic mechanisms (intrinsic/extrinsic)     of AMR will be discussed and phenomenological approaches explained.
