متن کاملSpin transition in LaCoO3 investigated by resonant soft X-ray emission spectroscopy
– The spin transition in LaCoO3 is investigated by temperature-dependent resonant soft X-ray emission spectroscopy near the Co 2p absorption edges. This element-specific technique is more bulk sensitive with respect to the temperature-induced spin state of the Co ions in LaCoO3 than other high-energy spectroscopic methods. The spin transition is interpreted and discussed with ab initio density-...
متن کاملSpin state transition in LaCoO3 studied using soft x-ray absorption spectroscopy and magnetic circular dichroism.
Using soft x-ray absorption spectroscopy and magnetic circular dichroism at the Co-L(2,3) edge, we reveal that the spin state transition in LaCoO3 can be well described by a low-spin ground state and a triply degenerate high-spin first excited state. From the temperature dependence of the spectral line shapes, we find that LaCoO3 at finite temperatures is an inhomogeneous mixed-spin state syste...
متن کاملUltrafast dynamics of strong-field dissociative ionization of CH2Br2 probed by femtosecond soft x-ray transient absorption spectroscopy
Femtosecond time-resolved soft x-ray transient absorption spectroscopy based on a high-order harmonic generation source is used to investigate the dissociative ionization of CH2Br2 induced by 800 nm strong-field irradiation. At moderate peak intensities (2.0 × 10 W/cm), strong-field ionization is accompanied by ultrafast C–Br bond dissociation, producing both neutral Br (P3/2) and Br* (P1/2) at...
