spin valves Latest News

Spin-valve storage of data in magnetic heads by the change in resistance from the alignment of electron spins is superseded by the dramatic superconductivity from charge carriers created by the conservation of Joule heat by QED

Current-induced switching in spin-valves by transfer of electron spin angular momentum is superseded by dramatic changes in photoconductivity by the photoelectric effect brought about by the QED induced conversion of Joule heat to EUV radiation
