I was an undergraduate student at Department of Materials Science and Engineering, Zhejiang University before July 1999, then I joined Department of Materials Science and Engineering after awarding the PhD degree by Zhejiang University at March 2004. I was academic visitor at Inorganic Chemistry Laboratory, University of Oxford from June 2011 to May 2012.
My current research interests include the novel ferroelectric materials predicted by the first-principle calucations and synthesized by the ceramic process, room-temperature electrocaloric effects in lead-free ferroelectric ceramics and giant dielectric response at high frequency.
Hybrid improper ferroelectricity in Ruddlesden-Popper Ca3(Ti,Mn)2O7 ceramics
The improper ferroelectrics are focused since they can avoid the exclusive of electronic configures between the proper ferroelectricity and magnetism in the multiferroic materials. We have successfully obtained the dense Ca3(Ti,Mn)2O7 ceramics by a standard solid state sintering process based on the previous first-principle results. The hybrid improper ferroelectricity was confirmed in this work. For the detail, please see the paper: X.Q. Liu, et al., Appl. Phys. Lett., 106 (2015) 202903.
