Abstract in English

We investigate the zero-temperature phase diagrams of the bilayer square-lattice Kugel-Khomskii (d^{9}) model involving entangled and singlet phases using mean-field cluster approach. This diagram includes interlayer singlet phase observed in copper fluoride K_{3}Cu_{2}F_{7} and exotic entangled spin-orbital phases. For a monolayer case, realized in K_{2}CuF_{4}, we perform similar calculations at finite temperature and show that the alternating-orbital ferromagnet decays first to an entangled uniform ferromagnet and then to a paramagnet.
