Finding the space group for PZT thin film XRD analysis

[fahad abdullah]

I have the XRD image of a PZT thin film. While trying to analyze it with JADE software I can not find the proper space group.So it is not giving me the answer I am looking for. I assumed the crystal system to be cubic.

Piezoelectric materials are never cubic - they cannot be centro-symmetric.

PZT has a perovskite crystal structure.
