Abstract
The exact results for thermodynamical properties of one-dimensional spin-1/2 isotropic XY model with Dzyaloshinskii-Moriya interaction in random lorentzian transverse field are obtained. This permits to discuss some approximate methods of disordered spin systems theory. The approximate scheme of examining the thermodynamics of one-dimensional spin-1/2 XXZ Heisenberg model with Dzyaloshinskii-Moriya interaction in random lorentzian field is suggested.
