ABSTRACT

This chapter is devoted to the physical effects basic to the operation of Hall and magnetoresistance devices. These effects are called the Hall effect and the magnetoresistance effect.

The Hall effect is the generation of a transverse electromotive force in a sample carrying an electric current and exposed to a perpendicular magnetic field. Depending on the sample geometry, this electromotive force may cause the appearance of a transverse voltage across the sample, or a current deflection in the sample. The generation of this transverse voltage, called the Hall voltage, is the generally known way for the appearance of the Hall effect [1].
