A combined X-ray and neutron-powder diffraction study of a superstructure derived from Tl0.75Sr1.8Ba0.2CuOy

Abstract:

We have observed a superstructure derived from the compound Tl0.75Sr1.8Ba0.2CuO(y). This compound arises from the 'collapse' of the parent oxynitrate compound TlSr2Ba2Cu2O7 (NO3) under controlled thermal decomposition. A combined X-ray and neutron powder diffraction study of the title compound indicates that the superstructure possesses the Pmmm space group, with unit cell parameters (derived from neutron diffraction data) of a = 3.7362(3) Å, b = 11.5449(9) Å, and c = 9.1494(8) Å. This supers...
