Deterministic switching of ferromagnetism at room temperature using an electric field
John T. Heron,James L. Bosse,Qing He,Ya Gao,Morgan Trassin,Linghan Ye,James D. Clarkson,Chen Wang,Jian Liu,Sayeef Salahuddin,Daniel C. Ralph,Darrell G. Schlom,Jorge Íñiguez,Bryan D. Huey,Ramamoorthy Ramesh +14 more
TL;DR: The kinetics of the switching process is examined, something not considered previously in theoretical work, and a deterministic reversal of the DM vector and canted moment using an electric field at room temperature is shown.
Journal ArticleDOI
Probing electric field control of magnetism using ferromagnetic resonance
Ziyao Zhou,Morgan Trassin,Ya Gao,Yuan Gao,Diana Y. Qiu,Khalid Ashraf,Tianxiang Nan,Xi Yang,Samuel R. Bowden,Daniel T. Pierce,Mark D. Stiles,John Unguris,Ming Liu,Brandon M. Howe,Gail J. Brown,Sayeef Salahuddin,Ramamoorthy Ramesh,Nian X. Sun +17 more
TL;DR: Electric field-dependent ferromagnetic resonance measurements quantify the exchange coupling strength and reveal that the CoFe magnetization is directly and reversibly modulated by the applied electric field through a ~180° switching of the canted moment in BiFeO3.
Journal ArticleDOI
A Strain-Driven Antiferroelectric-to-Ferroelectric Phase Transition in La-Doped BiFeO3 Thin Films on Si
Deyang Chen,Deyang Chen,Christopher T. Nelson,Xiaohong Zhu,Claudy Serrao,James D. Clarkson,Zhe Wang,Ya Gao,Shang-Lin Hsu,Liv R. Dedon,Zuhuang Chen,Di Yi,Heng Jui Liu,Dechang Zeng,Ying-Hao Chu,Jian Liu,Darrell G. Schlom,Ramamoorthy Ramesh +17 more
TL;DR: These findings provide direct evidence of spin-charge-lattice coupling in La-doped BiFeO3 thin films and opens a new pathway to drive the AFE-FE O-R phase transition and provides a route to study the O/R MPB in these films.
Journal ArticleDOI

Xiaopei Zhu,Ya Gao,Peng Shi,Ruirui Kang,Fang Kang,Wenjing Qiao,Jinyan Zhao,Zhe Wang,Ye Yuan,Xiaojie Lou +9 more
TL;DR: In this article , an ultrahigh recoverable energy density (Wrec) of 8.46 J/cm3 with excellent efficiency of 85.9% under 522 kV/cm is obtained in 0.90(Bi 0.5Na0.5)0.65Sr0.35TiO3-0.10
Journal ArticleDOI
Enhanced energy storage performance of 0.88(0.65Bi0.5Na0.5TiO3-0.35SrTiO3)-0.12Bi(Mg0.5Hf0.5)O3 lead-free relaxor ceramic by composition design strategy
Xiaopei Zhu,Peng Shi,Ya Gao,Ruirui Kang,Jian-Zhuang Zhao,and Yufang Xiao,Wenjing Qiao,Jinyan Zhao,Zhe Wang,Xiaojie Lou +9 more
TL;DR: In this paper , the influence of solid solution of SrTiO3 and Bi(Mg0.5Hf 0.5)O3 doping on crystal structure, microstructure, electrical and energy storage performance were evaluated systematically.
