Improper ferroelectricity in ultrathin hexagonal ferrites film
Xin Li, Yu Yun, Xiaoshan Xu
The suppression of ferroelectricity in ultrathin films of improper ferroelectric hexagonal ferrites or manganites has been attributed to the effect of interfacial clamping, however…
Intrinsic ferroelectricity in Y-doped HfO2 thin films
Yu Yun, Pratyush Buragohain, Ming Li +10
Ferroelectric HfO2-based materials hold great potential for widespread integration of ferroelectricity into modern electronics due to their robust ferroelectric properties at the n…
Textured organic ferroelectric films from physical vapor deposition and amorphous-to-crystalline transition
Yifan Yuan, Yuanyuan Ni, Xuanyuan Jiang +2
Crystallization is a key for ferroelectricity which is a collective behavior of microscopic electric dipoles. On the other hand, uncontrolled crystallization leads to uneven morpho…
Colossal intrinsic exchange bias in epitaxial CoFe2O4/Al2O3 thin films
Detian Yang, Yu Yun, Arjun Subedi +4
In this work, we demonstrate a massive intrinsic exchange bias (3 kOe) in epitaxial CoFe2O4(111) thin films deposited on Al2O3(0001) substrates. This exchange bias is indicative of…
Magnetoelectric coupling and decoupling in multiferroic hexagonal YbFeO3 thin films
Yu Yun, Xin Li, Arashdeep Singh Thind +9
The coupling between ferroelectric and magnetic orders in multiferroic materials and the nature of magnetoelectric (ME) effects are enduring experimental challenges. In this work,…
Interface ferromagnetism and anomalous Hall effect of CdO/ferromagnetic insulator heterostructures
Yang Ma, Yu Yun, Yuehui Li +8
The experimental observation of quantum anomalous Hall effect (QAHE) in magnetic topological insulators has stimulated enormous interest in condensed-matter physics and materials s…
Role of La doping for Topological Hall Effect in Epitaxial EuO Films
Yu Yun, Yang Ma, Tang Su +6
We report the critical role of La doping in the topological Hall effect observed in LaxEu1-xO thin films (~ 50 nm) grown by molecular beam epitaxy. When the La doping exceeds 0.036…
The Role of Oxygen in Ionic Liquid Gating on 2D Cr2Ge2Te6: a Non-Oxide Material
Yangyang Chen, Wenyu Xing, Xirui Wang +10
Ionic liquid gating can markedly modulate the materials' carrier density so as to induce metallization, superconductivity, and quantum phase transitions. One of the main issues is…
Observation of long phase-coherence length in epitaxial La-doped CdO thin films
Yu Yun, Yang Ma, Songsheng Tao +9
The search for long electron phase coherence length, which is the length that an electron can keep its quantum wave-like properties, has attracted considerable interest in the last…
Probe of Spin Dynamics in Superconducting NbN Thin Films via Spin Pumping
Yunyan Yao, Qi Song, Yota Takamura +7
The emerging field of superconductor (SC) spintronics has attracted intensive attentions recently. Many fantastic spin dependent properties in SC have been discovered, including th…
