Figure 3
Mn 2p X-ray absorption spectra for (a) La0.46Sr0.54MnO3 and (b) Nd0.46Sr0.54MnO3. The vertical dashed line indicates the absorption edge, which corresponds to EF in metallic samples. A large increase in the intensity just above EF with decreasing temperature was observed only for La0.46Sr0.54MnO3. |
