Magnetoresistance applications
WebMagnetoresistance (MR) is the effect that the resistance changes when a magnetic field is applied. It is usually small in metals, with Δ ρ / ρ of the order of 0.1–1% T − 1 . Recently, … WebIn certain materials, the application of a 7 T magnetic field can result in a 13 order of magnitude decrease in the electrical resistivity (“turning wood into silver”) Issues in colossal magnetoresistance (CMR) manganese oxides: – The effect of oxidation state in Ln 1 xA MnO 3 where Ln is a trivalent rare-earth (Ln = La, Pr, Nd
