Abstract

In present paper the hexagonal ferromagnetic semiconductor nanowires in which the atomic layers of two different material alternate are investigated by Green function method. In addition, the inter-layer spins coupling are taken differently. The analytical expressions of the dispersion equations for spin waves propagating along the axes of the structure under consideration are obtained. The dependences of spin wave frequencies on wave vector are investigated for the concrete choice of parameters. Spin waves propagating at both low and high frequencies are generated. The spin wave frequencies increase as exchange coupling between localized spin and also spins of conduction electrons.
