Topological phase transitions and Berry-phase hysteresis in exchange-coupled nanomagnets
Ahsan Ullah, Xin Li, Yunlong Jin +6
Topological phase in magnetic materials yields a quantized contribution to the Hall effect known as the topological Hall effect, which is often caused by skyrmions, with each skyrm…
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…
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…
Perpendicular Magnetic Anisotropy in Conducting NiCo2O4 Films from Spin-Lattice Coupling
Corbyn Mellinger, Jace Waybright, Xiaozhe Zhang +2
High perpendicular magnetic anisotropy (PMA), a property needed for nanoscale spintronic applications, is rare in oxide conductors. We report the observation of a PMA up to 0.23 MJ…
Nonvolatile Multilevel States in Multiferroic Tunnel Junctions
Mei Fang, Sangjian Zhang, Wenchao Zhang +6
Manipulation of tunneling spin-polarized electrons via a ferroelectric interlayer sandwiched between two ferromagnetic electrodes, dubbed Multiferroic Tunnel Junctions (MFTJs), can…
Structural phase diagram and magnetic properties of Sc-substituted rare earth ferrites R1-xScxFeO3 (R=Lu, Yb, Er, and Ho)
Jason White, Kishan Sinha, Xiaoshan Xu
We have studied the structural stability of Sc-substituted rare earth (R) ferrites R1-xScxFeO3, and constructed a structural phase diagram for different R and x. While RFeO3 and Sc…
