Abstract
Bulk Tl2Ba2Ca2Cu3Ox superconductor was synthesized and oxygenated. The critical temperature was determined to be 116.5 K from resistivity, 117.5 K from AC susceptibility (intra-grain) and 115.0 K from AC susceptibility (inter-grain). The critical current at 77.3 K, utilizing a non-contact Bean’s method, is 189 A/cm2. After oxygenation, the sample contained 60% mass of the desired compound (X-ray diffraction measurement). The critical exponent in the closest vicinity of the critical temperature occurred to be 0.112 (AC susceptibility) and 0.259 (resistance). Further, from the critical temperature the susceptibility exponent was determined to be 0.779 and the resistance critical exponent was equal to 1.13.
