Band structure and spin texture of BiSe/3d ferromagnetic metal interface
Jia Zhang, Julian P. Velev, Xiaoqian Dang +1
The spin-helical surface states in three-dimensional topological insulator (TI), such as Bi2Se3, are predicted to have superior efficiency in converting charge current into spin po…
Bias dependence of tunneling magnetoresistance in magnetic tunnel junctions with asymmetric barriers
Alan Kalitsov, Pierre-Jean Zermatten, Frédéric Bonell +5
The transport properties of magnetic tunnel junctions (MTJs) are very sensitive to interface modifications. In this work we investigate both experimentally and theoretically the ef…
Electric-field-induced magnetization changes in Co/Al2O3 granular multilayers
Ajeesh M. Sahadevan, Alan Kalitsov, Gopinadhan Kalon +3
We study experimentally the effect of electric field on the magnetization of Co/Al2O3 granular multilayers. We observe two distinct regimes: (a) low-field regime when the net magne…
Ferroelectric Dead Layer Driven by a Polar Interface
Y. Wang, M. K. Niranjan, K. Janicka +4
Based on first-principles and model calculations we investigate the effect of polar interfaces on the ferroelectric stability of thin-film ferroelectrics. As a representative model…
Oxide tunnel junctions supporting a two-dimensional electron gas
J. D. Burton, J. P. Velev, E. Y. Tsymbal
The discovery of a two-dimensional electron gas (2DEG) at the interface between insulating oxides has led to a well-deserved level of excitement due to possible applications as "in…
Magnetic tunnel junctions with ferroelectric barriers: Prediction of four resistance states from first-principles
Julian P. Velev, Chun-Gang Duan, J. D. Burton +5
Magnetic tunnel junctions (MTJs), composed of two ferromagnetic electrodes separated by a thin insulating barrier layer, are currently used in spintronic devices, such as magnetic…
