Abstract

Neutron diffraction studies of the title materials have been performed at 600K, R.T. and 8K. Copper and iron ions are randomly distributed in two equivalent MO2 planes being the symmetry P4/mmm for all the samples and temperatures. Some extra oxygen has been found in PrBaCuFeO5+δ destroying the AF ordering, present at R. T. in YBaCuFeO5. Besides this, at low temperature a magnetic phase transition has been found. On the other hand, both materials show a complex micro-structure as determined by electron diffraction.
