Fig. 2: Characterization of a Nd2Ir2O7 thin film.

a High-resolution XRD pattern of a 15 nm thick Nd2Ir2O7 (NIO-227) thin film. The NIO-227 thin film was grown on a YSZ substrate. b Reciprocal space map of the NIO-227 film in the vicinity of the YSZ (331) reflection, indicating that the NIO-227 film is fully strained. c The plot of the longitudinal resistivity, ρxx, vs. temperature, T, of NIO-227 thin film and single crystal (ref. 46 in the main manuscript). d The AHE is measured by applying Hext along the [111] direction and I along the [1\(\bar{{{{{1}}}}}\)0] direction at 2 K. A clear AHE without a magnetic field is the signature of the presence of the T1-octupole in the NIO-227 thin film.
