Spin waves in multiple-spin-density-wave systems
Journal of Physics C: Solid State Physics, 1986The spin wave modes in an anisotropic Heisenberg model are investigated for a triple-spin-density-wave (TSDW) ground state in a FCC lattice. Explicit solutions are obtained in the diagonal-exchange regime in all directions. The solutions are also given in the (0,0, xi ) and ( xi , xi ,0) directions for the above model including non-diagonal exchange ...

Spin waves in itinerant multiple-spin-density-wave systems. II
Journal of Physics F: Metal Physics, 1987For pt.I see ibid., vol.17, no.5, p.1175 (1987). The spin wave energies and widths for linear- (LSDW) and multiple-spin-density-wave (MSDW) systems are calculated using the formalism developed in pt.I for an itinerant model. Calculations were made for the wave-vector q parallel and perpendicular to the magnetisation in the LSDW state; the velocities ...

Spin-wave/Carrier-wave interactions
IEEE Transactions on Electron Devices, 1970The possibility of spin-wave/carrier-wave interactions has been considered with a more rigorous stability analysis than that used in previous studies. It is concluded that unstable bulk interactions in magnetic semiconductors will not be possible until resistivities are reduced to several orders of magnitude below those presently available.
