Phenomenological description of a spin chain system with geometrical frustration of couplings
The phenomenological model, using which we can in a relatively simple way calculate many magnetic, thermo-dynamic and dynamic characteristics of the spin chain material with the geometrical frustration of spin-spin couplings is proposed. The results of theoretical calculations well reproduce observe...
