A MRAM device is fabricated using magnetic graphene oxide- iron oxide nanoparticles nanocomposites together with a platinum electrode and a ferromagnetic cobalt electrode. The device allow for a positive magnetoresistance up to 280% via the spin-dependent trapping of charge carriers. Its low resista...
