a Close-up view of the optical conductivity as a function of temperature. The red shaded area represents the fitting results. The data are offset for clarity. b–g Frequency vs. temperature for six representative phonons. Individual points are obtained from fits to σ1(ω) in a, and the dotted lines represent a fit to typical anharmonic behavior36,37. The magnetic ordering temperature is indicated by the gray vertical line at 74 K. Unless indicated, error bars are smaller than the symbol size.
