1. Quantum Mechanics and Spin-Valves

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
