Electrical observation via spin Seebeck effect of fractionalized excitations in a magnetic insulator
Nan Tang, Josef Willsher, Stephan Glamsch +9
Fractionalized excitations are among the most striking signatures of emergence in quantum matter. While widely sought in frustrated magnets, their detection and characterization re…
The Evolution of Magnetism in a Thin Film Pyrochlore Ferromagnetic Insulator
Margaret A. Anderson, Megan E. Goh, Yang Zhang +19
The pyrochlore vanadates are compelling candidates for next-generation dissipationless devices. Lu2V2O7 and Y2V2O7 are ferromagnetic insulators (Tc ~ 70 K) that are believed to exh…
Floating zone growth of high-purity MgO substrate single crystals
Christo Guguschev, Michael Schulze, Andrea Dittmar +5
MgO single crystals with diameters between 3.5 and 5 mm and lengths up to 40 mm were grown by the optical floating zone technique (OFZ). Despite challenging material properties suc…
Observation via spin Seebeck effect of macroscopic magnetic transport from emergent magnetic monopoles
Nan Tang, Stephan Glamsch, Aisha Aqeel +7
Magnetic monopoles, elusive in high-energy physics, have been realised as emergent quasiparticles in solid-state systems, where their unique properties hold promise for novel spint…
