Interface-Induced Stability of Nontrivial Topological Spin Textures: Unveiling Room-Temperature Hopfions and Skyrmions
F. Katmis, V. Lauter, R. Yagan +9
Topological spin configurations, such as soliton-like spin texture and Dirac electron assemblies, have emerged in recent years in both fundamental science and technological applica…
Absence of Magnetic Fluctuations in the Ferromagnetic/Topological Heterostructure EuS/BiSe
Gavin B. Osterhoudt, Ryan Carelli, Ferhat Katmis +3
Heterostructures of topological insulators and ferromagnets offer new opportunities in spintronics and a route to novel anomalous Hall states. In one such structure, EuS/BiSe…
Direct measurement of proximity-induced magnetism at the interface between a topological insulator and a ferromagnet
Changmin Lee, Ferhat Katmis, Pablo Jarillo-Herrero +2
When a topological insulator (TI) is in contact with a ferromagnet, both time reversal and inversion symmetries are broken at the interface. An energy gap is formed at the TI surfa…
Band structure of topological insulators from noise measurements in tunnel junctions
Juan Pedro Cascales, Isidoro Martınez, Ferhat Katmis +4
The unique properties of spin-polarized surface or edge states in topological insulators (TIs) make these quantum coherent systems interesting from the point of view of both fundam…
Electric coupling in scanning SQUID measurements
Eric M. Spanton, Aaron J. Rosenberg, Yihua H. Wang +5
Scanning SQUID is a local magnetometer which can image flux through its pickup loop due to DC magnetic fields (). Scanning SQUID can also measure a sample's magnetic response to…

Exploiting 2D materials for spintronic applications can potentially realize next-generation devices featuring low-power consumption and quantum operation capability. The magnetic e…
Coherent ultrafast spin-dynamics probed in three dimensional topological insulators
F. Boschini, M. Mansurova, G. Mussler +12
Topological insulators are candidates to open up a novel route in spin based electronics. Different to traditional ferromagnetic materials, where the carrier spin-polarization and…
Inducing magnetism onto the surface of a topological crystalline insulator
Badih A. Assaf, Ferhat Katmis, Peng Wei +4
Inducing magnetism onto a topological crystalline insulator (TCI) has been predicted to result in several novel quantum electromagnetic effects. This is a consequence of the highly…

We theoretically investigate the surface plasmon polariton (SPP) at the interface between 3D strong topological insulator (TI) and layered superconductor-magnetic insulator structu…
Quantum Coherent Transport in SnTe Topological Crystalline Insulator Thin Films
Badih A. Assaf, Ferhat Katmis, Peng Wei +6
Topological crystalline insulators (TCI) are unique systems where a band inversion that is protected by crystalline mirror symmetry leads to a multiplicity of topological surface s…
Linear magnetoresistance in topological insulators: Quantum phase coherence effects at high temperatures
Badih A. Assaf, Thomas Cardinal, Peng Wei +3
In addition to the weak antilocalization cusp observed in the magnetoresistance (MR) of topological insulators at low temperatures and low magnetic fields, we find that the high-fi…
