Title: Coupling of spin waves with charge- and spin-density excitations in spin-polarized quantum wells

Abstract

The coupling of spin waves with charge- and spin-density waves is shown to be induced by a spin-dependent interaction in a quantum well, which is spin polarized by a dc magnetic field at an angle {theta} to the symmetry axis. The mixing of the plasmonic and magnonic modes, which occurs for both intra- and intersubband transitions, depends on the coupling constant of the spin-spin interaction, the tilt angle {theta}, and the initial spin polarization {zeta}. (c) 1999 The American Physical Society.
