High pressure X ray diffraction studies up to 15GPa were performed on the Y doped Bi2212 compound with the rare earth concentrationx=0.1at 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. ©1999 American Institute of Physics.
