Phonons Reflect Dynamic Spin-State Order in LaCoO 3

We investigate lattice dynamics in LaCoO3 using inelastic neutron and x-ray scattering over T ¼ 2 − 650 K, spanning the spin-state crossover at T1 ≈ 100 K and the insulator-metal transition at T2 ≈ 550 K. Comparison with quasiharmonic ab initio lattice-dynamical calculations help...

Thermal decomposition and dehydration mechanism of kurnakovite MgB3O3(OH)5·5H2O

Abstract The thermal decomposition and dehydration mechanism of kurnakovite MgB3O3(OH)5·5H2O, a hydrated Mg borate mineral with potential industrial applications, were investigated using thermal analysis, in-situ high-temperature synchrotron single-crystal X-ray diffraction (30–1...
