Figure 5
Temperature dependence of the HeI UPS valence band spectra for (a) (La0.8Nd0.2)0.46Sr0.54MnO3 and (b) Nd0.46Sr0.54MnO3. The backgrounds were subtracted by using the Shirley method, and the spectra were normalized by the maximum intensity. A large change in the shape of the spectrum at about 4–6 eV, which is indicated as the energy-range between the dotted lines, occurred across TC = 260 K only for (La0.8Nd0.2)0.46Sr0.54MnO3.
