In a new study published in Nature Physics, scientists have achieved the first experimental observation of phonon angular momentum in chiral crystals.

Paul Haney and Mark Stiles of the CNST have developed a theory of current-induced torques that generalizes the relationship between spin transfer torques, total angular momentum current, and ...

By conservation of angular momentum, a change in the direction of an electron spin angular momentum leads to a torque on the magnetization of the ferromagnet.
