Ak. Ghosh et An. Basu, REDUCTION IN DIFFERENCE OF THE RESISTIVE AND MAGNETIC CRITICAL-TEMPERATURE IN IRRADIATED (BI,PB)-2223 SUPERCONDUCTORS, Modern physics letters B, 12(2-3), 1998, pp. 91-97
The resistive and magnetic critical temperatures of alpha-irradiated (
Bi,Pb)-2223 superconductors are measured from resistivity and the real
part of the ac susceptibility. Difference in these two critical tempe
ratures are found to be decreased with irradiation monotonically. Chan
ge in difference of these two temperatures with irradiation are discus
sed in this paper.
