Abstract
Superstructure due to ordering of vacancies in Nd2-xSrxCuO4-y (x=1.2-1 .5) was investigated by XRD and TEM. There exist different ordering ty pes in the same sample. After fluorination reaction, the ordering stru cture disappears. F doping induces superconductivity in Nd0.7Sr1.3CuO4 -delta (T-c=44K). No SrF2 was observed in the fluorinated products.
