Anisotropic magnetoresistance (AMR) A material property leading to the increase of electrical resistance when the direction of current is parallel to the applied magnetic field. Discovered by Lord Kelvin this effect is only found in Ferromagnetic materials and results from changes to the orientations of the electron orbitals. In a Semiconductor with a single carrier type, the magetoresistance is proportional to (1+ (μ''B'')2), where μ is the Semiconductor Mobility (units m2V-1s-1 or Tesla-1) and B is the magnetic field (units Tesla). |
