Sentences with phrase «flows of electron spins»

The effect and its brethren — with names like the spin Hall effect, the spin Seebeck effect and the spin Peltier effect — allow scientists to create flows of electron spins, or spin currents.

Not exact matches

In an ordinary superconductor, electrons, which carry a spin of 1/2, pair up and flow uninhibited with the help of vibrations in the atomic structure.

Neutrons are ideal tools for identifying and characterizing magnetism in almost any material, because they, like electrons, exhibit a flow of magnetism called «spin.»

In this configuration the lead forms «islands» below the graphene and the electrons of this two - dimensional material behave as if in the presence of a colossal 80 - tesla magnetic field, which facilitates the selective control of the flow of spins.

In a conventional superconductor electrons with opposite spins are paired together so that a flow of electrons carries zero spin.

Now, the same researchers have found a set of materials which encourage the pairing of spin - aligned electrons, so that a spin current flows more effectively in the superconducting state than in the non-superconducting (normal) state.

Then, McCamey says, the researchers use millimeter - wave radiation to tweak the spin of the electrons while monitoring the current flowing through.

This suggests that the electrons flowing through the tiny passage have their spin degree of freedom broken, just as electrons in a ferromagnet don't have the freedom to point in any direction but are lined up in a coordinated way.
