Orbital excitations in titanates

C. Ulrich, A. Gössling, M. Grüninger +6

Raman scattering is used to observe pronounced electronic excitations around 230 meV - well above the two-phonon range - in the Mott insulators LaTiO $_{3}$ and YTiO $_{3}$ . Based on the…

Determination of the orbital moment and crystal field splitting in LaTiO $_{3}$

M. W. Haverkort, Z. Hu, A. Tanaka +18

Utilizing a sum-rule in a spin-resolved photoelectron spectroscopic experiment with circularly polarized light, we show that the orbital moment in LaTiO $_{3}$ is strongly reduced bot…

A different look at the spin state of Co $^{3 +}$ ions in CoO $_{5}$ pyramidal coordination

Z. Hu, Hua Wu, M. W. Haverkort +10

Using soft-x-ray absorption spectroscopy at the Co- $L_{2, 3}$ and O- $K$ edges, we demonstrate that the Co $^{3 +}$ ions with the CoO $_{5}$ pyramidal coordination in the layered Sr $_{2}$ …
