Evolution of charge and spin state of transition metals in the LaMn1-xCoxO3 perovskite serie
Charge and spin state evolution of the transition metals in the LaMn1-xCoxO3 Spectroscopy. The high spin of the Mn3+/4+ and Co2+ ions is preserved in the entire solidsolution. Co3+ ions reveal low spin

Thermally and field driven spin-state transitions in (Pr1-yYy)Ca0.3CoO3./sub
The first-order character of the transition from the low- to - intermediate spin state in the system (Pr(1-y)Yy)Ca0.3CoO3 (y=0.075-0.15) has been verified by magnetization measurements.For y=0.075, the transition m...

Excitonic instability at the spin-state transition in the two-band Hubbard model
Using linear response theory with the dynamical mean-field approximation we investigate the particle-hole instabilities of the two-band Hubbard model in the vicinity of the spin-state transition. Besides the previously repo...

Incommensurate interactions and nonconventional spin-Peierls transition in TiOBr
The temperature-dependent x-ray diffraction experiments show that TiOBr undergoes two pahse transitions upon cooling. The first leads to an incommensurately modulated phase and the second is a lock-in transition into a spin...

Evolution of the phonon density of states of LaCoO3 over the spin state transition
found to be in a reasonable agreement. The evolution of the phonon density of states over the spin state transition was analyzed. In the low-temperature range (T < 50 K to the spin state tran...

Disproportionation and metallization at low-spin to high-spin transition in multiorbital Mott systems
We study the thermally driven spin state transition in a two-orbital Hubbard Carlo impuritysolver. At intermediate temperatures we find a spin disproportionated phase characterized by a checkerboard order of sites ...
