Electric-field control of spin-orbit torque in a magnetically doped topological insulator
Yabin Fan, Xufeng Kou, Pramey Upadhyaya +16
Electric-field manipulation of magnetic order has proved of both fundamental and technological importance in spintronic devices. So far, electric-field control of ferromagnetism, m…
Nanoscale -Nuclear Magnetic Resonance Depth Imaging of Topological Insulators
Dimitrios Koumoulis, Gerald D. Morris, Liang He +8
Considerable evidence suggests that variations in the properties of topological insulators (TIs) at the nanoscale and at interfaces can strongly affect the physics of topological m…
Magnetism-induced massive Dirac spectra and topological defects in the surface state of Cr-doped BiSe-bilayer topological insulators
C. -C. Chen, M. L. Teague, L. He +6
Proximity-induced magnetic effects on the surface Dirac spectra of topological insulators are investigated by scanning tunneling spectroscopic (STS) studies of bilayer structures c…
Origin of interfacial perpendicular magnetic anisotropy in MgO/CoFe/metallic capping layer structures
Shouzhong Peng, Mengxing Wang, Hongxin Yang +9
Spin-transfer-torque magnetic random access memory (STT-MRAM) attracts extensive attentions due to its non-volatility, high density and low power consumption. The core device in ST…
Electric-field guiding of magnetic skyrmions
Pramey Upadhyaya, Guoqiang Yu, Pedram Khalili Amiri +1
We theoretically study equilibrium and dynamic properties of nanosized magnetic skyrmions in thin magnetic films with broken inversion symmetry, where electric field couples to mag…
Resonant magneto-optic Kerr effect in the magnetic topological insulator Cr:(Sb,Bi)Te
Shreyas Patankar, J. P. Hinton, Joel Griesmar +10
We report measurements of the polar Kerr effect, proportional to the out-of-plane component of the magnetization, in thin films of the magnetically doped topological insulator $(\t…
