Excited and ground state properties of LaSrMnO4: A combined x-ray spectroscopic study

The electronic properties of the parent compound of the single layered manganites La1−xSr1+xMnO4, namely LaSrMnO4 has been investigated in a detailed spectroscopic study.
We apply different complementary x-ray spectroscopic techniques in the soft x-ray regime. X-ray photoelectron spectroscopy and normal like x-ray emission spectroscopy were used to reveal a detailed picture of the total and partial densities of states in this compound. Furthermore we apply resonant x-ray emission spectroscopy to the Mn L2,3 edges. The spectra exhibit a rich multiplet structure. Resonant x-ray emission spectroscopy at the O K edge is used to study the local partial densities of states of the in plane and out of plane oxygen atoms. The results are discussed along available band structure calculations as well as charge transfer multiplet calculations.
