= Extraordinary magnetoresistance
{wiki=Extraordinary_magnetoresistance}
Extraordinary magnetoresistance (EMR) is a phenomenon observed in certain materials, particularly in materials that have a complex interplay between their electronic structure and magnetic properties. EMR is characterized by a large change in electrical resistance when exposed to an external magnetic field. This effect is particularly notable in materials with a layered structure, such as certain ferromagnets or half-metals.
