The 329th forum: New chemistry and physics in magnetic oxides

Date: 2018-05-09
Time: 10:00
Venue: 中科院物理研究所M楼253报告厅
Speaker: Prof. J. Paul Attfield

Centre for Science at Extreme Conditions and School of Chemistry,
University of Edinburgh

Paul Attfield holds a Chair in Materials Science at Extreme Conditions at the School of Chemistry and Centre for Science at Extreme Conditions, University of Edinburgh. He received B.A. and D.Phil. degrees from Oxford University, and he was a Co-Director of the Interdisciplinary Research Centre in Superconductivity at the University of Cambridge during 1991-2003. He received the Royal Society of Chemistry’s Meldola and Corday-Morgan medals and Peter Day award, and he was elected a Fellow of the Royal Society in 2014. Early research contributions included pioneering resonant X-ray scattering experiments of cation and valence ordering, and studies of disorder effects in functional oxides. Current research is centred on electronic and magnetic materials including use of high pressure methods.

Early concepts of magnetism emerged from studies of magnetic minerals, notably magnetite (Fe3O4). Today we know of many types of magnetism and magnetic materials, but transition metal oxides remain important as they are based on abundant, non-toxic elements and can offer large magnetisations at room temperature. They have also been investigated intensively for coupling of magnetism to other phenomena, for example, to electronic conductivity for spintronic materials; to ferroelectricity in multiferroics; and to lattice thermodynamics in magnetocalorics. This talk will present new chemical and physical aspects of spintronic oxides.
