Mössbauer and optical spectrometry of selected schörl-dravite tourmalines
Spectrometric studies were carried out on samples of tourmaline (schörl-dravite series) from geological environments where first-phase-formed tourmaline underwent influence of geochemically differentExpand

Photoinduced Ferrimagnetic Systems in Prussian Blue Analogues CIxCo4[Fe(CN)6]y (CI = Alkali Cation). 1. Conditions to Observe the Phenomenon
Photoinduced magnetization has been recently evidenced by Hashimoto et al. in CoFe Prussian blue analogues. We synthesized three compounds with a variable cobalt environment to point out theExpand

Monte Carlo entropic sampling applied to spin crossover solids: the squareness of the thermal hysteresis loop
Abstract The Monte Carlo entropic sampling method previously presented in [ I. Shteto, J. Linares, F. Varret, Phys. Rev. E 56 (1997) 5128 ] is adapted here to an Ising-like system with short- andExpand

Photoinduced ferrimagnetic systems in Prussian blue analogues C(I)xCo4[Fe(CN)6]y (C(I) = alkali cation). 3. Control of the photo- and thermally induced electron transfer by the [Fe(CN)6] vacancies in
We synthesized a series of CoFe Prussian blue analogues along which we tuned the amount of cesium cations inserted in the tetrahedral sites of the structure. Structure and electronic structure haveExpand

Raman spectroscopy of the high- and low-spin states of the spin crossover complex Fe(phen) 2 (NCS) 2 : an initial approach to estimation of vibrational contributions to the associated entropy change
Abstract Raman spectra of the spin-crossover complex Fe(phen) 2 (NCS) 2 in the solid state have been recorded at 785 nm as a function of temperature to investigate the contribution of intramolecularExpand

Dynamic triggering of a spin-transition by a pulsed magnetic field
Abstract:We report the first study of the effect of a high pulsed magnetic field on a spin transition complex in the solid state. The high spin fraction was determined by optical reflectivity.Expand

Photo-excitation from dia- to ferri-magnetism in a Rb-Co-hexacyanoferrate Prussian blue analogue
Abstract:We studied the photo-excitation process, the relaxation of the photo-excited state towards the stable state, and the photo-induced magnetic properties of the Prussian blue analogue Rb0.52CoExpand

The kinetics features of a thermal spin transition characterized by optical microscopy on the example of [Fe(bbtr)3](ClO4)2 single crystals: Size effect and mechanical instability
We investigated by optical microscopy the thermal spin transition in single crystals of [Fe(bbtr)3](ClO4)2 (bbtr = 1,4-di(1,2,3-triazol-1-yl) butane). The growth of the low-spin phase was observedExpand

Velocity of the high-spin low-spin interface inside the thermal hysteresis loop of a spin-crossover crystal, via photothermal control of the interface motion.
We investigated by optical microscopy the thermal transition of the spin-crossover dinuclear iron(II) compound [(Fe(NCSe)(py)(2))(2)(m-bpypz)]. In a high-quality crystal the high-spin (HS) low-spinExpand

Structure-driven orientation of the high-spin-low-spin interface in a spin-crossover single crystal.
The orientation of the high-spin (HS)-low-spin (LS) macroscopic interface at the thermal transition of thin [{Fe(NCSe)(py)2}2(m-bpypz)] crystals is explained by considering the possible vanishing ofExpand
