The paper presents a characterization of the phase structure by X-ray diffraction and isothermal magnetic entropy changes for the amorphous Fe₅₈Co₁₀Zr₁₀Mo₅W₂B₁₅ alloy sample in the as-quenched state. An ingot sample was obtained by arc-melting. The ribbon sample was obtained by the melt-spinning technique. The magnetic measurements at various temperatures allowed for the study of the Curie temperature T_{C} and magnetic entropy changes |ΔS_{M}|. In order to determine the Curie temperature T_{C} of amorphous phase, three independent methods were used. Determination of the Curie temperature T_{C} for the amorphous alloys is not a trivial problem, as magnetization does not decreases rapidly around T_{C}. Therefore it is essential issue to establish T_{C} using few complementary methods. X-ray diffraction analysis revealed a fully amorphous structure of the ribbon samples.
