Multiferroic material is a class of materials containing more than one ferroic order. Ferroelectric magnetic multiferroic materials contain simultaneous polarization and magnetization. The separated ferroic orders and the coupling between them make the multiferroic material the great potential for application in memory devices and sensors. BiFeO₃, as a multiferroic material with simultaneous ferroelectricity and magnetism above room, has attracted great attention in the past years. I will talk about our recent works in the field of ferroic materials, including

1.Single phase multiferroic materials, including BiFeO₃ and BiFe_0.5Mn_0.5O₃, and BTFO₁₅

2.Magnetoelectric coupling

3.Spin dynamics in multiferroics

4.Magnetoelectric caloric materials

Z. X. Cheng received B.S. in Physics in 1995, a M.S. in solid state physics in 1998 and a PhD in material science in 2001, from the Department of Physics and the State Key Lab. of Crystal Materials, Shandong University. He accepted a research fellow position at the Institute for Superconducting and Electronic Materials (ISEM) of University of Wollongong in 2002. He is a JSPS (Japanese Society for Promotion of Science) fellow at National Institute for Material Science (NIMS) in Japan during 2003-2005. At the end of 2005, he returned to ISEM as a research Fellow. Due to his outstanding performance he was awarded the highly prestigious Future Fellowship from the Australia Research Council in 2009, and promoted to an Associate Professor in 2010.

     Cheng has published more than 200 SCI journal papers in the field of applied physics with more than 2700 citations. More than 60 papers appear on the prestigious journals, like Physical Review Letters (PRL), Nano Letters, J. American Chemical Society, Angewandte Chemie, Advanced Healthcare Materials, Phys. Rev. B (PRB), Applied Physics Letters (APL), Chemistry Communication and Scientific Reports. He has more than 40 invited talks on international conferences, workshops and universities.
