(a) Mn L-edge absorption spectra, (b) In 4d, (c) Te 4d and (d) Sb 4d core-level spectra of a-MIST, MIST_1 and MIST_2 samples. A shoulder was enhanced at 639 eV photon energy (at the arrow) in Mn L-edge spectrum of MIST_2. Binding energies of Te and Sb 4d5/2 are 40.2 and 31.7 eV, respectively. These peaks are not changed during phase-transitions.
