Higher-order Weyl nodes driven by helical magnetic order in EuAgAs
Jian-Rui Soh, Ziming Zhu, Louis Withers +8
Magnetic topological semimetals provide a fertile ground for exploring how long-range magnetic order can alter electronic band structures and generate novel quasiparticles such as…

Fluctuation-driven topological Hall effect in room-temperature itinerant helimagnet Fe3Ga4
Priya R. Baral, Victor Ukleev, Ivica ŽivkoviÄ +12
The topological Hall effect (THE) is a hallmark of a non-trivial geometric spin arrangement in a magnetic metal, originating from a finite scalar spin chirality (SSC). The associat…

Crystal structure and absence of magnetic order in single crystalline RuO
Lara Kiefer, Felix Wirth, Alexandre Bertin +7
RuO was considered for a long time to be a paramagnetic metal with an ideal rutile-type structure down to low temperatures, but recent studies on single-crystals claimed eviden…
