Magnetoresistance

Like other magnetoresistive effects, GMR is the change in electrical resistance in response to an applied magnetic field. Transition metals are extensively ...

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 history of the research on magnetoresistance effect is described first and then the basis of electron conduction is explained.

Hall-effect sensing elements generate a voltage that is proportional to the magnitude of a nearby magnetic field. Hall sensor technology is an application of ...

A magnetoresistive sensor uses the fact that the electrical resistance in a ferromagnetic thin film alloy is changed through an external magnetic field. “Ferrum ...

A magnetoresistive sensor consists of a resistor made of magnetically sensitive alloy strips such as nickel iron (NiFe).

Either a resistance variation or a voltage (planar Hall efect) caused by a magnetic field is the physical quantity utilized.

They detect changes, or disturbances in magnetic fields that have been created or modified by objects or events. The magnetic fields may therefore carry ...

磁阻效應（英語：Magnetoresistance，簡稱MR），是指材料的電阻隨著外加磁場之變化而改變的效應，其物理量的定義，是在有無磁場下的電阻差除上原先電阻，用以代表電阻變化率。
