We report on the synthesis of low doping Zn_1-xCo_xO (0<x<0.1) thin films on (0001)-Al_2O_3 substrates. The films were prepared in an oxidizing atmosphere, using the pulsed laser deposition technique starting from Zn and Co metallic targets. We first studied the influence of the strains of ZnO and their stuctural properties. Second, we have investigated the structural and the magnetic properties of the Zn_1-xCo_xO films. We show that at low doping, the lattice parameters and the magnetization
