Emergent giant topological Hall effect in twisted Fe3GeTe2 metallic system
Hyuncheol Kim, Kai-Xuan Zhang, Yu-Hang Li +3
The topological Hall effect, driven by the exchange interaction between conduction electrons and topological magnetic textures such as skyrmions, is a powerful probe for investigat…
High-speed antiferromagnetic domain walls driven by coherent spin waves
Kyle L. Seyler, Hantao Zhang, Daniel Van Beveren +4
The ability to rapidly manipulate domain walls (DWs) in magnetic materials is key to developing novel high-speed spintronic memory and computing devices. Antiferromagnetic (AFM) ma…
Anisotropic Field Suppression of Morin Transition Temperature in Epitaxially Grown Hematite Thin Films
Haoyu Liu, Hantao Zhang, Josiah Keagy +5
We have demonstrated the existence of the Morin transition in epitaxially grown hematite thin films exceeding a critical thickness. The Morin transition temperature can be suppress…
Coherent Spin Pumping Originated from Sub-Terahertz Néel Vector Dynamics in Easy Plane α-Fe2O3/Pt
Gregory Fritjofson, Atul Regmi, Jacob Hanson-Flores +5
We present a thorough study of spin-to-charge current interconversion in bulk and thin films of (0001) α-Fe2O3 /Pt heterostructures by means of all-optical polarization-controlled…
