The shape of Brillouin zone of body-centered cubic crystal is not normal dodecahedron;

By Matsubara-Green function method,the magnon damping under such on interaction is studied,with the magnon damping calculated on the main symmetric point/line in Brillouin zone for different parameters in the system.

The magonon spectrum is studied through Matsubara-Green function, and the magnon dispersion curve is calculated on the main symmetric point and line in Brillouin zone for different parameters in the system.
