Physical properties of Gd_2Cu_{2 - x}Co_{x}In (x = 0.1, 0.2, 0.3) samples are investigated. The paper brings results of X-ray diffraction, magnetometric as well as specific heat studies. It was found that only sample with x = 0.1 exhibits desired crystal structure. Other compositions show existence of impurities due to lack of dissolution Co atoms. For Gd_2Cu_{1.9}Co_{0.1}In sample the Curie temperature of 92.5 K was evidenced. Thus, an enhancement of ferromagnetic correlations with comparison to Gd_2Cu_2In sample was evidenced. It was found that Gd_2Cu_{1.9}Co_{0.1}In sample exhibits magnetocaloric effect within broad temperature range.
