Proximity Magnetism in Mn(Bi,Sb)2Te4-(Bi,Sb)2Te3/MnTe Natural Heterostructures
Owen A. Vail, Shu-Wei Wang, Yasen Hou +13
Magnetic topological insulators and their heterostructures provide great opportunities in coupling band topology with nontrivial spin configuration for enhanced spintronic device p…
Conductivity scaling of the anomalous Hall effect in the altermagnetic semiconductor α-MnTe
Sara Bey, Shelby S. Fields, Nicholas G. Combs +22
α-MnTe is a prototypical altermagnet exhibiting a strong anomalous Hall effect (AHE), despite having a nearly vanishing magnetization. Lately, sample-to-sample variations of the a…
Anisotropy-driven interfacial magnetism in Ru-deficient SrRuO thin films
VÃtor A. de Oliveira Lima, Michael I. Faley, Asmaa Qdemat +9
While stoichiometric SrRuO (SRO) is a metallic itinerant ferromagnet with relatively homogeneous magnetization, Ru deficiency provides a powerful route to alter its electronic…
Emergence of unconventional magnetic order in strain-engineered RuO2/TiO2 superlattices
Seung Gyo Jeong, Seungjun Lee, Jin Young Oh +8
The spin ordering in RuO2 remains a highly debated topic, owing to its elusive nature, with reports ranging from a nonmagnetic ground state to signatures of unconventional magnetic…
Non-Altermagnetic Origin of Exchange Bias Behaviors in Incoherent RuO/Fe Bilayer Heterostructures
Shelby S. Fields, Joseph C. Prestigiacomo, Cory D. Cress +14
Initially identified as a promising altermagnetic (AM) candidate, rutile RuO has since become embroiled in controversy due to contradictory findings of modeling and measurement…
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…
