Whenever we can get the spin of an atom to move: whenever we can get a spin to lose OR gain energy, that energy can be transferred to an electron with high efficiency. There are a number of ways that atomic spin can be excited: magnetocaloric where heat energy is transferred to the spin of an atom embedded in a lattice through metal lattice phonons of that lattice or quantum mechanical vibrations that are inherent in the heisenberg uncertainty principle. The key is to amplify this naturally occurring spin movements enough to move electrons strong enough to generate usable voltages and currents. That amplification mechanism might be done by setting up a coherence boundary condition that involves a change of state between coherence and incoherence where a slight external magnetic perturbation triggers this change of state.
Barium ferrite might be a magnetic current superconductor where magnetic currents flow inside its lattice. An example of this magnetic current superconductor might be a magnet that allows magnetic flux lines to pass through it or not based on an external parameter: may be temperature or an external magnetic perturbation as an example. See (Barium ferrite is a magnetic insulator) http://www.nature.com/nmat/journal/v16/n3/full/nmat4812.html Current-induced switching in a magnetic insulator The spin Hall effect in heavy metals converts charge current into pure spin current, which can be injected into an adjacent ferromagnet to exert a torque. This spin–orbit torque (SOT) has been widely used to manipulate the magnetization in metallic ferromagnets. In the case of magnetic insulators (MIs), although charge currents cannot flow, spin currents can propagate, but current-induced control of the magnetization in a MI has so far remained elusive. Here we demonstrate spin-current-induced switching of a perpendicularly magnetized thulium iron garnet film driven by charge current in a Pt overlayer. We estimate a relatively large spin-mixing conductance and damping-like SOT through spin Hall magnetoresistance and harmonic Hall measurements, respectively, indicating considerable spin transparency at the Pt/MI interface. We show that spin currents injected across this interface lead to deterministic magnetization reversal at low current densities, paving the road towards ultralow-dissipation spintronic devices based on MIs.
