Y. Nishi et al., INFLUENCE OF AR ION ETCHING ON T-C OF LIQUID-QUENCHED BI1.6PB0.4SR2CA2CU3OX SUPERCONDUCTOR BY SHEET PLASMA SOURCE, Journal of Materials Science, 31(11), 1996, pp. 2893-2896
The influence of argon-ion etching is investigated for liquid-quenched
high-T-c Bi1.6Pb0.4Sr2Ca2Cu3Ox. The argon-ion irradiation has no effe
ct on the T-c value for a dose of 4.05 x 10(17) (ions mm(-2)). However
, doses in excess of this level greatly decreases the T-c value. There
fore, a critical irradiation does value (D-c) to maintain a T-c value
above 100 K is defined and determined. The D-c is about 4.94 x 10(17)
(ions mm(-2)) for argon-ion irradiation at the low acceleration energy
of 1 keV.
