Magnetic-photoconductive material, magneto-optical data storage device, magneto-optical data storage system, and light-tunable microwave components comprising a photoconductive-ferromagnetic device

The present invention concerns a magnetic-photoconductive material including orientable magnetic moments or spins, the material being configured to generate photo-carriers permitting to orientate or re-orientate the magnetic moments or spins at a material temperature less than the Curie Temperature (TC) or Curie point.
