Abstract

The authors theoretically propose microscopic mechanism of conversion between the electron spin and microscopic local rotations of atoms in crystals. In phonon modes with angular momenta, the atoms rotate around their equilibrium positions in crystals. The authors show that spin magnetization is generated by the microscopic local rotation of atoms via the spin-orbit interaction.
