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…
Hanle-effect measurements of spin injection from Mn5Ge3C0.8/Al2O3-contacts into degenerately doped Ge channels on Si
Inga Anita Fischer, Li-Te Chang, Christoph Sürgers +7
We report electrical spin injection and detection in degenerately doped n-type Ge channels using Mn5Ge3C0.8/Al2O3/n^{+}-Ge tunneling contacts for spin injection and detection. The…
Scale-Invariant Dissipationless Chiral Transport in Magnetic Topological Insulators beyond the Two-Dimensional Limit
Xufeng Kou, Shih-Ting Guo, Yabin Fan +12
We investigate the quantum anomalous Hall Effect (QAHE) and related chiral transport in the millimeter-size (Cr0.12Bi0.26Sb0.62)2Te3 films. With high sample quality and robust magn…
Switching of perpendicular magnetization by spin-orbit torques in the absence of external magnetic fields
Guoqiang Yu, Pramey Upadhyaya, Yabin Fan +10
Magnetization switching by current-induced spin-orbit torques (SOTs) is of great interest due to its potential applications for ultralow-power memory and logic devices. In order to…
Edge effect on resistance scaling rules in graphene nanostructures
Guangyu Xu, Carlos M. Torres, Jianshi Tang +6
We report an experimental investigation of the edge effect on the room-temperature transport in graphene nanoribbon and graphene sheet (both single-layer and bilayer). By measuring…
Enhanced Conductance Fluctuation by Quantum Confinement Effect in Graphene Nanoribbons
Guangyu Xu, Carlos M. Torres, Emil B. Song +5
Conductance fluctuation is usually unavoidable in graphene nanoribbons (GNR) due to the presence of disorder along its edges. By measuring the low-frequency noise in GNR devices, w…
