term: magnetic nanostructure


an artificial heterostructure characterised by giant or tunnel magnetoresistance that is a multilayer film made up of alternating layers of ferromagnetic non-magnetic materials.


For example, alternating layers of nanostructure Co–Ni–Cu/Cu are the ferromagnetic layer Co–Ni–Cu and the non-magnetic layer Cu. The thickness of these layers is on the order of the electron free path, i.e. several nanometres. Changing the intensity of the externally applied magnetic field from ...
