American  

noun

Physics.

1. a magnetic wave propagated through a crystal lattice by a collective excitation of the spin angular momentum of electrons.

Etymology

Origin of spin wave

First recorded in 1935–40

Example Sentences

"What's special about YIG is that it propagates a magnetic spin wave," says Olsson, referring to the type of wave created in magnetic materials when electrons spin in a synchronized fashion.

That supercurrent acts as a mirror for the spin wave: the superconducting electrode reflects the magnetic field back to the spin wave.
