The structural, magnetic and magnetocaloric properties in the Gd doped MnCo1-xGdxGe alloys were investigated. With the increase of Gd content, the coexistence of Ni2In-type hexagonal structure and TiNiSi-type orthorhombic structure appear from the pure Ni2In-type hexagonal structure of MnCoGe. All samples undergo the second-order magnetic transition (SOMT). MnCo1-xGdxGe (x= 0.04, 0.06) have two successive magnetic transitions and a large reversible table-like MCE has been achieved around room temperature (RT). Moreover, the relative cooling power (RCP) and effective refrigeration temperature span (δTFWHM) with the magnetic field change of 50 kOe reach 335 J/kg and 128 K, respectively.
