Unconventional unidirectional magnetoresistance in heterostructures of a topological semimetal and a ferromagnet
Nature Materials, Published online: 21 March 2025; doi:10.1038/s41563-025-02175-0
Unconventional unidirectional magnetoresistance observed in the heterostructures of a topological semimetal (WTe2) and a magnetic insulator (Cr2Ge2Te6) enables the electrical read-out of the magnetic states of a perpendicularly polarized magnet through longitudinal resistance measurements.
