Influence of Sn-substitution on structural, superconducting and magnetic properties of EuBa₂Cu₃O_{7-δ} (Eu-123) compound was studied by X-ray diffraction and SQUID magnetic measurements. Transition process from normal to superconducting state and temperature dependences of zero field cooling and field cooling characteristics of magnetic moment and magnetization curves were measured and analysed. Samples of the nominal composition of EuBa₂Cu_{3-x}Sn_xO_{7-δ} with x ranging from 0.0 to 1.5 were prepared by the solid state reaction technique. The increasing Sn-content decreases the volume of the main superconducting phase (Eu-123) and for higher Sn-contents, semiconducting tetragonal Eu₃Ba₃Cu₆O₁₄(Eu-336) and Ba-Sn-O phases are the dominant ones.
