Anisotropic magnetoresistance

(AMR - anisotropic magneto resistance), also called an anomaly magnetorezystancyjnego pheno menon is a phenomenon occurring in the ferromagnetic metals and a lloys, revealing a change in resistance under the influence of re orientation of magnetization of the material terms of the direction of current flowing through it. This phenomenon is characterized by the fact that changes in electrical resistance occur at a much lower intensities of the magnetic field than is the case in the ordinary magnetoresistance. The largest observed amplitude of the AMR effect over 50% at low temperatures. The heads read information carried in most of the material used, ie
