a Temperature-dependent χmT product and light-induced spin transition effect induced by laser. The measurements were performed with a sweeping rate of 2 K min−1. Temperature-dependent χmT product before (blue) and after irradiation (red) with 532 nm laser light in the heating mode. b 57Fe Mössbauer spectra at room temperature and 50 K, respectively.
