High pressure X ray diffraction studies of rare earth doped Bi 2212 system

摘要

High pressur X ray diffraction studies up to 15GPa were performed on the Y doped Bi2212 compound with the rare earth concentration x chemical bounds 0.1 at the calcium site. From the studies it has been found that the system remains in the orthorhombic structure up to 15GPa. The relative volume is found to decrease around 15GPa. This may be a positive indication for a pressure induced structural transition in the system beyond 15GPa.
