Unveiling temperature dependence mechanisms of perpendicular magnetic anisotropy at Fe/MgO interfaces
Fatima Ibrahim, Ali Hallal, Alan Kalitsov +3
The perpendicular magnetic anisotropy (PMA) at magnetic transition metal/oxide interfaces is a key element in building out-of-plane magnetized magnetic tunnel junctions for spin-tr…
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…
Tunneling behavior of bismuth telluride nanoplates in electrical transport
Mustafa Eginligil, Weiqing Zhang, Alan Kalitsov +2
We study the electrical transport properties of ensembles of bismuth telluride (Bi2Te3) nanoplates grown by solution based chemical synthesis. Devices consisting of Bi2Te3 nanoplat…
The role of charge traps in inducing hysteresis: capacitance - voltage measurements on top gated bilayer graphene
Gopinadhan Kalon, Young Jun Shin, Viet Giang Truong +2
Understanding the origin of hysteresis in the channel resistance from top gated graphene transistors is important for transistor applications. Capacitance - voltage measurements ac…
Voltage induced control and magnetoresistance of noncollinear frustrated magnets
A. Kalitsov, M. Chshiev, B. Canals +1
Noncollinear frustrated magnets are proposed as a new class of spintronic materials with high magnetoresistance which can be controlled with relatively small applied voltages. It i…
Voltage Dependence of Spin Transfer Torque in Magnetic Tunnel Junctions
M. Chshiev, I. Theodonis, A. Kalitsov +2
Theoretical investigations of spin transfer torque in magnetic tunnel junctions using the tight-binding model in the framework of non-equilibrium Green functions formalism are pres…
Impurity-induced tuning of quantum well states in spin-dependent resonant tunneling
A. Kalitsov, A. Coho, N. Kioussis +3
We report exact model calculations of the spin-dependent tunneling in double magnetic tunnel junctions in the presence of impurities in the well. We show that the impurity can tune…
