Electrical detection of topological magnetic textures such as skyrmions is currently limited to conducting materials. While magnetic insulators offer key advantages for skyrmion technologies with high speed and low loss, they have not yet been explored electrically. Here, we report a prominent topological Hall effect in Pt/TmFeO bilayers, where the pristine TmFeO epitaxial films down to 1.25 unit cell thickness allow for tuning of topological Hall stability over a broad range from 200 to 465 K through atomic-scale thickness control. Although TmFeO is insulating, we demonstrate the detection of topological magnetic textures through a novel phenomenon: "spin-Hall topological Hall effect" (SH-THE), where the interfacial spin-orbit torques allow spin-Hall-effect generated spins in Pt to experience the unique topology of the underlying skyrmions in TmFeO. This novel electrical detection phenomenon paves a new path for utilizing a large family of magnetic insulators in future skyrmion technologies.

A transcriptional activator that contains five adjacent CYS2-HIS2 ZINC FINGERS. It functions in the hedgehog signaling pathway and is required for normal embryonic development. Mutations in the GLI2 gene are associated with type 9 HOLOPROSENCEPHALY and type 2 PALLISTER-HALL SYNDROME.
A technique for detecting short-lived reactive FREE RADICALS in biological systems by providing a nitrone or nitrose compound for an addition reaction to occur which produces an ELECTRON SPIN RESONANCE SPECTROSCOPY-detectable aminoxyl radical. In spin trapping, the compound trapping the radical is called the spin trap and the addition product of the radical is identified as the spin adduct. (Free Rad Res Comm 1990;9(3-6):163)

A pleiotropic disorder of human development that comprises hypothalamic HAMARTOMA; central and postaxial POLYDACTYLY; bifid EPIGLOTTIS; ANAL ATRESIA; and renal and other abnormalities. This disorder is associated with FRAMESHIFT MUTATIONS in the GLI3 gene which encodes the GLI3 protein, a KRUPPEL-LIKE TRANSCRIPTION FACTORS family member.
