Fangwei Wang

Fangwei Wang has been working as a researcher in the field of magnetism and neutron scattering at Institute of Physics, CAS, after getting his PhD there in 1997, and became a full professor in 2005. He worked temporarily at HKUST (Hong Kong), LLB/Saclay (France) and ORNL (USA) as a visiting scholar. His research interest includes neutron scattering instrumentation and application, data analysis and visualization, magneto- calorics/resistance/capacity, magnetism in strongly correlated oxides and alloys, and clean energy materials, particularly by using neutron scattering technique, and published more than 160 papers in peer reviewed journals.
He investigated permanent magnetism and magentocaloric effect in rare-earth transition-metal compounds, magnetoresistance and magnetocapacity in oxides, and macroscopic quantum effect in magnetic molecular. A strong axial anisotropy and a significant enhancement of Curie temperature were found in the permanent magnet candidate, the arc-melting intermetallics R2(Fe,Ga)17Cx. Large magnetic entropy changes were found in RAl2, La(Fe,M)13 (M=Al,Si), and CdCr2S4, (Tb,Gd)Al2 can be an potential magnetic refrigerant in the temperature range of 80–160 K, filling up the gaps required by the eight stage magnetic refrigerator. A strong coupling along the degrees of freedom, lattice, orbital, spin and charge in the bilayer manganite were experimentally verified by multiple neutron scattering techniques. Crystallographic characteristics of Li ion in the battery anode materials Li2MnO3 and LiFePO4 were checked out with neutron diffraction.
Since joining the China Spallation Neutron Source (CSNS) in 2003, he has served as the leader of neutron science division, and conducted the design of CSNS target station and neutron instruments. As schedule, CSNS bursted the first neutron beam in August,2017, three dayone instruments recorded the first neutrons and the genereal purpose powder diffractometer collected its first diffraction pattern in November, 2017. Now CSNS has finished its construction and will be regularly opened to users soon.
He also serve as vice director of China Neutron Scattering Society and the member of council of Chinese Physics Society, of Material Genome Committee, and of Academic Committee of Institute of Physics (CAS), China, also the observer and the representative of CSNS facility in Asia-Oceania Neutron Scattering Association (AONSA).
