Their structural, superconducting and magnetic characteristics were analyzed based on the results of polarizing optical microscopy, XRD and SQUID magnetometric measurements. Increasing tin content reduces the volume of the main superconducting phase. The critical superconducting temperature decreases from 95 K for x = 0 to 82 K for x = 0.7. For higher tin content, the semiconductor tetragonal phase Eu-336 (Eu3Ba3Cu6O14), paramagnetic or diamagnetic Ba-Sn-O phase dominate. The usefulness of measuring ZFC and FC temperature dependences of magnetic characteristics in the study of systems characterized by the simultaneous presence of superconducting and magnetic arrangements and in distinguishing their effects has been demonstrated.<\/span><\/p>\n<p><span class=\"tlid-translation translation\" lang=\"en\"><br \/>\n<strong>Foreign partner:<\/strong><br \/>\n\u2022 Department of Inorganic and Physical Chemistry, Faculty of Sciences, Ghent University, Belgium.<br \/>\nRelated projects:<br \/>\n\u2022 VEGA 2\/0152\/13: Development of SQUID Gradiometric and Susceptometric Methods for Bioapplications Associated with Iron Homeostasis Related<br \/>\n\u2022 ASFEU project 26240120019 (CENTE II).<br \/>\n\u2022 project AI5 \/ TT \/ 1170.<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Publication:<\/strong><\/p>\n<p><u>DVURE\u010cENSKIJ, A.<\/u> &#8211; <u>CIG\u00c1\u0147, A.<\/u> &#8211; VAN DRIESSCHE, I. &#8211; <u>\u0160KR\u00c1TEK, M.<\/u> &#8211; <u>MAJEROV\u00c1, M.<\/u> &#8211; BRUNEEL, E. &#8211; <u>MA\u0147KA, J<\/u>.
