Excitation of spin waves on a cylindrical semiconductor heterostructure with Rashba spin-orbit interaction
arXiv:0811.3070 · doi:10.1016/j.physe.2008.11.005
Abstract
Elementary excitations in a paramagnetic semiconductor quantum well confined to a cylindrical surface are theoretically studied on the basis of coupled spin-charge drift-diffusion equations. The electric-field-mediated eigenmodes are optically excited by an oscillating interference pattern, which induces a current in the outer circuit. For a cylinder with a given radius, sharp resonances are predicted to occur in the steady-state current response, which are due to weakly damped spin remagnetization waves.
