magnetic impurities

Magnetic impurities are tiny amounts of metals, like iron or cobalt, introduced into a non-magnetic material. These impurities have unpaired electrons that create tiny magnetic fields, disrupting the normal behavior of the host material. They can affect the material’s electrical, magnetic, and thermal properties by interacting with the surrounding atoms. For example, in metals or semiconductors, magnetic impurities can influence conductivity and magnetism, which is important in designing electronic devices and understanding material behavior at the microscopic level.
