dc.description.abstractThe magnetic properties of pyrochlore-type Bi1.89Fe1.16Nb0.95O6.95 have been investigated for the first time using AC and DC susceptibility. The compound is shown to behave as a classical spin glass due to strong competition/coexistence of ferro- and antiferromagnetic exchange. The study was accompanied by the first-ever growth of single crystals of this compound using the floating-zone method, allowing us to carry out a single-crystal neutron diffraction experiment that confirmed and extended our understanding of local structural disorder, driven by the stereochemically active 6s2 electron lone pair on Bi3 + ions. The magnetic properties are discussed in terms of both the topologically frustrated Fe3 + lattice and the role of this local structural disorder. © 2010, Institute of Physicsen_AU
