Magnetic molecule tunnel heterojunctions
Xuanyuan Jiang, Andrew Brooks, Shuanglong Liu +6
We characterize molecular magnet heterojunctions in which sublimated CoPc films as thin as 5 nm are sandwiched between transparent conducting bottom-layer indium tin oxide and top-…
Thickness-dependent spin bistable transitions in single-crystalline molecular 2D material
John Koptur-Palenchar, Miguel Gakiya-Teruya, Duy Le +7
The advent of two-dimensional (2D) crystals has led to numerous scientific breakthroughs. Conventional 2D systems have in-plane covalent bonds and a weak out-of-plane van-der-Waals…
Persistent Ionic Photo-responses and Frank-Condon Mechanism in Proton-transfer Ferroelectrics
Xuanyuan Jiang, Xiao Wang, Pratyush Buragohain +8
Photoexcitation is well-known to trigger electronic metastable states and lead to phenomena like long-lived photoluminescence and photoconductivity. In contrast, persistent photo-r…
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…
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,…
Probe Ferroelectricity by X-ray Absorption Spectroscopy in Molecular Crystal
Fujie Tang, Xuanyuan Jiang, Hsin-Yu Ko +8
We carry out X-ray absorption spectroscopy experiment at oxygen K-edge in croconic acid (C5H2O5) crystal as a prototype of ferroelectric organic molecular solid, whose electric pol…
Effects of biaxial strain on the improper multiferroicity in h-LuFeO3 films
Kishan Sinha, Yubo Zhang, Xuanyuan Jiang +11
Elastic strain is potentially an important approach in tuning the properties of the improperly multiferroic hexagonal ferrites, the details of which have however been elusive due t…
Room Temperature Ferroelectricity in Continuous Croconic Acid Thin Films
Xuanyuan Jiang, Haidong Lu, Yuewei Yin +10
Ferroelectricity at room temperature has been demonstrated in nanometer-thin quasi 2D croconic acid thin films, by the polarization hysteresis loop measurements in macroscopic capa…
On the Structural Origin of the Single-ion Magnetic Anisotropy in LuFeO3
Shi Cao, Xiaozhe Zhang, Tula R. Paudel +12
Electronic structures for the conduction bands of both hexagonal and orthorhombic LuFeO3 thin films have been measured using x-ray absorption spectroscopy at oxygen K (O K) edge. D…
