EFFECTS ON TC AND JC IN THE (TL0.5PB0.5)SR2CACU2OY SUPERCONDUCTOR OF PARTIAL DOPING OF CA SITES BY NATURAL MISCHMETAL OXIDES
A new high-Tc superconductor of monophasic composition (Tl0.5Pb0.5)Sr2(Ca0.9M0.1)Cu2Oy (M representing mischmetal) has been produced. As a result, Tc (as measured by resistivity and magnetic means) has been increased to 100K, 20K greater than in the parent (Tl0.5Pb0.5)Sr2CaCu2Oy phase. However, magn...
