Fermi Level Dependent Spin Pumping from a Magnetic Insulator into a Topological Insulator
Hailong Wang, James Kally, Cuneyt Sahin +7
Topological spintronics aims to exploit the spin-momentum locking in the helical surface states of topological insulators for spin-orbit torque devices. We address a fundamental qu…
Low temperature saturation of phase coherence length in topological insulators
Saurav Islam, Semonti Bhattacharyya, Hariharan Nhalil +7
Implementing topological insulators as elementary units in quantum technologies requires a comprehensive understanding of the dephasing mechanisms governing the surface carriers in…
Imaging the stochastic microstructure and dynamic development of correlations in perpendicular artificial spin ice
Susan Kempinger, Robert D. Fraleigh, Paul Lammert +4
We use spatially resolved magneto-optical Kerr microscopy to track the complete microstates of arrays of perpendicular anisotropy nanomagnets during magnetization hysteresis cycles…
Non-Majorana Origin of the Half-Quantized Conductance Plateau in Quantum Anomalous Hall Insulator and Superconductor Hybrid Structures
Morteza Kayyalha, Di Xiao, Ruoxi Zhang +14
A quantum anomalous Hall (QAH) insulator coupled to an s-wave superconductor is predicted to harbor a topological superconducting phase, the elementary excitations of which (i.e. M…
Observation of Interfacial Antiferromagnetic Coupling between Magnetic Topological Insulator and Antiferromagnetic Insulator
Fei Wang, Di Xiao, Wei Yuan +13
Inducing magnetic orders in a topological insulator (TI) to break its time reversal symmetry has been predicted to reveal many exotic topological quantum phenomena. The manipulatio…
