Pressure-induced charge orders and their coupling to magnetism in hexagonal multiferroic LuFe2O4
Fengliang Liu, Yiqing Hao, Jinyang Ni +13
Hexagonal LuFe2O4 is a promising charge-order (CO) driven multiferroic material with high charge and spin ordering temperatures. The coexisting charge and spin orders on Fe3+/Fe2+…
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…
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…
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…
