- The ground-state phase diagram of the Ising model on the Shastry-Sutherland lattice with the first ($J_1$), second ($J_2$), third ($J_3$) and fourth ($J_4$) nearest neighbour spin couplings is studied using the exact and well controlled numerical method. It is shown that switching on of the $J_3$ and $J_4$ interactions (in addition to usually considered $J_1$ and $J_2$ interactions) leads to stabilization of the following dominant magnetic phases with m/$m_s$=1/9, 1/6, 4/9, 1/2 and 5/9, which is manifested in appearance of new magnetization plateaus on the magnetization curve of the model at given values of m/$m_s$. The obtained results are consistent with experimental measurements of magnetization curves in selected rare-earth tetraborides.
