V. Bhat et Jm. Honig, FLUORINATION OF LA2-XSRXCUO4- EXHIBITION OF SUPERCONDUCTIVITY FOR X-LESS-THAN-OR-EQUAL-TO-0.05(DELTA ), Materials research bulletin, 30(10), 1995, pp. 1253-1261
La2-xSrxCuO4+delta with 0 less than or equal to x less than or equal t
o 0.4 was fluorinated. Nonsuperconducting samples with x less than or
equal to 0.05 were rendered superconducting after fluorination. T-c is
little affected for x greater than or equal to 0.1; low-field diamagn
etic properties are improved for these compositions.
