Mott-Hubbard versus charge-transfer behavior in LaSrMnO 4 studied via optical conductivity
Using spectroscopic ellipsometry, we study the optical conductivity σ(ω) of insulating LaSrMnO 4 in the energy range of 0.75-5.8eV from 15to330K. The layered structure gives rise to a pronounced anisotropy. A multipeak structure is observed in σa1(ω) (∼2, 3.5, 4.5, 4.9, and 5.5eV), while only one pe...
