  • Cooperative paramagnetism refers to a strongly correlated state without long range magnetic order that occurs in frustrated magnetic systems between the Neel temperature and Curie-Weiss temperature. Here, using resonant elastic magnetic and inelastic x-ray scattering, Terilli et al find a spectrally sharp gapped magnetic excitations that persists above the Neel temperature in Y2Ir2O7, implying a cooperative paramagnetic phase.

  • Pyrochlore iridates have been studied for their potential to explore novel phases due to the interplay of correlations, spin-orbit interaction, and more recently dimensionality. Here the authors report a chiral spin-liquid-like state in (111)-oriented Y2Ir2O7 thin films which emerges at a reduced thickness.
