Quantum Mechanics and Spin-Valves
Thomas Prevenslik QED Radiations, Discovery Bay, Hong Kong, CHINA Quantum mechanics precludes atoms in nanoscale ferromagnetic FM spin-valves from conserving Joule heat by an increase in temperature Instead, conservation proceeds by the QED induced creation of excitons (holon and electron pairs) in the FMs. The holons act as charge carriers that dramatically lower the GMR by large increases in electrical conductivity QED induced conductivity is significant suggesting superconductivity at ambient temperature may be possible in the FM layers. GMR reduction by electron-spin alignment is insignificant compared to QED induced conductivity
