Magnetoresistiviilmiö
Magnetoresistivity refers to the property of a material to change its electrical resistance in the presence of an external magnetic field. This phenomenon is a fundamental concept in condensed matter physics and has led to the development of various sensor technologies. The magnitude of the magnetoresistive effect can vary significantly between different materials.
There are several types of magnetoresistive effects. Anisotropic magnetoresistance (AMR) is observed in ferromagnetic materials where
