"large-scale integrated non-volatile highly durable, low energy consumption... spintronic magnetic random access memory where helical magnet directions of atomic magnetic moments ordered in chiral spiral (read out as resistance change, not magnetic fields)... magnetic fields cancel each other out, so the helical magnets do not generate any macroscopic magnetic field, free from ferrromagnet's crosstalk among bits improving memory density... room-temperature epitaxial thin films helimagnet MnAu2 and Pt bilayer device"
