Compositional Control and Optimization of Molecular Beam Epitaxial Growth of (Sb2Te3)x(MnSb2Te4)y Magnetic Topological Insulators
Ido Levy, Candice Forrester, Haiming Deng +6
Magnetic topological insulators such as MnBi2Te4 and MnSb2Te4 are promising hosts of novel physical phenomena such as quantum anomalous Hall effect and intrinsic axion insulator st…
Self-assembled Bismuth Selenide (Bi2Se3) quantum dots grown by molecular beam epitaxy
Marcel S. Claro, Abhinandan Gangopadhyay, David J. Smith +1
We report the growth of self-assembled Bi2Se3 quantum dots (QDs) by molecular beam epitaxy on GaAs substrates using the droplet epitaxy technique. The QD formation occurs after ann…
Above 400 K Robust Perpendicular Ferromagnetic Phase in a Topological Insulator
Chi Tang, Cui-Zu Chang, Gejian Zhao +8
The quantum anomalous Hall effect (QAHE) that emerges under broken time-reversal symmetry in topological insulators (TI) exhibits many fascinating physical properties for potential…
Nanoscale Magnetic Compasses
Hidetsugu Shiozawa, Desai Zhang, Michael Eisterer +4
We have synthesized nanoscale magnetic compasses with high yield. These ferromagnetic iron carbide nano-particles, which are encapsulated in a pair of parallel carbon needles, chan…
Domain structure and perpendicular magnetic anisotropy in CoFe/Pd multilayers using off-axis electron holography
Desai Zhang, Justin M. Shaw, David J. Smith +1
Multilayers of Co90Fe10/Pd with different bilayer thicknesses, have been deposited by dc-magnetron sputtering on thermally oxidized Si wafers. Transmission electron microscopy show…
Negative tunneling magnetoresistance by canted magnetization in MgO/NiO tunnel barriers
Hyunsoo Yang, See-Hun Yang, Dong-Chen Qi +6
The influence of insertion of an ultra-thin NiO layer between the MgO barrier and ferromagnetic electrode in magnetic tunnel junctions has been investigated by measuring the tunnel…
