Evidence of a Hybridized Topological State in Weyl Semimetal/Topological Insulator MnSn/BiSb Heterostructures
Ryan T. Van Haren, Gillian P Boyce, Gregory M. Stephen +4
We report magnetotransport evidence of a hybridized Weyl semimetal (WSM) Fermi arc/topological insulator (TI) surface state at the interface of a ferromagnetic MnSn…

Anomalous low-field magnetoresistance in FeGa single crystals
Michelle E. Jamer, Gregory M. Stephen, Brandon Wilfong +6
FeGa possesses a helical spin spiral with a complex competition between ferromagnetic and antiferromagnetic ground states. This competition generates multiple metamagnetic…

Probing Magnetic Properties of RuO Heterostructures Through the Ferromagnetic Layer
Frank M. Abel, Subhash Bhatt, Shelby S. Fields +20
RuO has been proposed as the prototypical altermagnetic material. However, several reports have recently questioned its intrinsic magnetic ordering, leading to conflicting fi…
