The effect manifests itself as a significant decrease (typically 10–. 80%) in electrical resistance in the presence of a magnetic field. The effect is exploited.
Giant magnetoresistance (GMR) is a quantum mechanical magnetoresistance effect observed in multilayers composed of alternating ferromagnetic and non-magnetic ...
Magnetoresistance is the tendency of a material (often ferromagnetic) to change the value of its electrical resistance in an externally-applied magnetic field. Giant magnetoresistance · Tunnel magnetoresistance · Colossal magnetoresistance
Experiments show that the application of a magnetic field increases the resistivity of a semiconductor and produces a decrease in the magnitude of the Hall ...
The phenomenon of the change of conductivity by the applied magnetic field is generically called a magnetoresistance effect. The contents are divided into the ...
These sensors can measure fields of less than 10−3 A/m up to several 104 A/m, i.e., much lower fields than normal Hall sensors. The relation between magnetic ...
Magnetoresistance (MR) is an important spintronic phenomenon characterized by a change in the resistance of a material upon exposed to a magnetic field.
