Relative to ferromagnetic metals, ferromagnetic semiconductors: enable one to realize devices that have no analogs among ferromagnetic metal devices; offer better performance (e.g. enhanced magnetic switching); and are more compatible with existing semiconductor technologies, notably in regards to .....
