Structure of the energetic spectrum and dispersion laws in tetragonal crystals of the class D4

  • Published:
Soviet Physics Journal Aims and scope

Abstract

The structure of the energetic spectrum of simple tetragonal crystals of the class D4 is investigated by the method of loaded co-representations. Parametric expressions are obtained for the dispersion laws in a quadratic approximation of the expansion in wave vector components. Spin-orbital interaction is taken into account.
