Studies of magnetic properties for the Gd₃Zr₁₀Fe₅₅Co₁₀Mo₅W₂B₁₅ glassy alloy are presented. The amorphous structure of melt-spun ribbon of investigated alloy was confirmed by X-ray diffractometry. The Curie temperature T_C was determined analyzing M(H) dependences measured at various temperatures as well as from M(T) dependence measured at low constant magnetic field. Furthermore, the isothermal magnetic entropy changes |-ΔS_M| were calculated from the magnetization curves to assess the possibility of potential application of studied samples as active elements in magnetic refrigerators.
