Voigt–Thomson_law
Voigt–Thomson law describes anisotropic magnetoresistance effect in a thin film strip as a relationship between the electric resistivity and the direction of electric current:[1]
where:
- is the angle of direction of current in relation to the direction of magnetic field
- is the initial resistivity
- is the change of resistivity (proportional to MR ratio)
The equation can also be expressed as:[2]
where:
- is the parallel component of resistivity
- is the perpendicular component
