我们报告的温度依赖性的光谱重量的重新分配的光电子能谱的La0.6Sr0.4MnO3在几个电子伏特的宽的能量范围。我们把这归因于铁磁有序度随温度的变化引起的电子关联强度的变化。我们讨论了费米能级附近随温度变化的谱权与反常输运性质之间的关系。
We report temperature-dependent redistribution of spectral weight in photoemission spectra of La0.6Sr0.4MnO3 over a wide energy range of several eV. We attribute this to a change in the electron correlation strength induced by the changing degree of ferromagnetic order with temperature. We discuss the relationship between the temperature-dependent spectral weight close to the Fermi level and the unusual transport properties.
