In this work we propose a quantum heat engine by using as working substance (WS) two particles of spin- 1/2 and spin-1 respectively. The proposed model is described by the Heisenberg XXZ model with the Dzyaloshinskii-Moriya (DM) interaction in the presence of magnetic field B. The analyse the influence on the efficiency and work of the (DM) interaction and the field is discussed.
