The tunnelling probability, and hence the resistance of the junction, depends on the relative orientation of the magnetization of the two magnetic ... hard ferromagnetic contacts, which deform ...

All objects fall at the same speed unless there is air resistance. Air resistance makes ... pole or two south poles will repel each other. Magnetic force can overcome gravity.

Giant magnetoresistance (GMR) is a quantum mechanical effect observed in thin film structures composed of alternating ferromagnetic and non-magnetic layers. It is characterized by a significant change ...
