Abstract
Superconducting properties of Sr2CuO2F2+delta have been measured as a function of synthesis parameters. Fluorination initiates above 160-deg rees-C, appears optimum near 180-degrees-C and is difficult to control above 250-degrees-C in forming superconducting samples. Optimum T(c) values are nominally 47 K; however, Meissner data show fluctuations ex tending to 60 K.
