Pb2FeReO6: new defect pyrochlore oxide with a geometrically frustrated Fe/Re sublattice†
Abstract
Nominal Pb2FeReO6 adopts a defect pyrochlore structure at ambient pressure unlike the other A2FeReO6
(A = Ca, Sr, Ba). Rietveld refinement of the crystal structure of one of the compositions Pb2FeReO6.1 from
