For the first time, thin films of NdBaCo_{2}O_{5+x} were deposited by RF magnetron sputtering on different substrates. The films deposited on SrLaAlO_4(001) substrates exhibited highly textured structure with c-axis directed out-of-plane. Magnetic measurements M vs. T of three NdBaCo_{2}O_{5+x}/SrLaAlO_4(001) films revealed successively paramagnetic-ferromagnetic-antiferromagnetic transitions with decrease in temperature. Their paramagnetic Curie-Weiss temperatures were estimated to be in the range of T_{C}=100-116 K. Resistivity of the cobaltite thin film exhibited insulating behavior and the best fit was found for the variable range hopping mechanism.
