2024 Roadmap on Magnetic Microscopy Techniques and Their Applications in Materials Science
D. V. Christensen, U. Staub, T. R. Devidas +50
Considering the growing interest in magnetic materials for unconventional computing, data storage, and sensor applications, there is active research not only on material synthesis…
Hidden spin-texture at topological domain walls drive exchange bias in a Weyl semimetal
Avia Noah, Filip Toric, Tomer D. Feld +11
Exchange bias is a phenomenon critical to solid-state technologies that require spin valves or non-volatile magnetic memory. The phenomenon is usually studied in the context of mag…
Non-contact mutual inductance based measurement of an inhomogeneous topological insulating state in Bi2Se3 single crystals with defects
Amit Jash, Kamalika Nath, T. R. Devidas +2
Pure Topological Insulating materials preserve a unique electronic state comprising of bulk insulating gap and conducting surface states. Here we use bulk Bi2Se3 single crystals po…
