Non-linear Relaxation of the Photo-induced High Spin State in Spin-crossover Solids: Effect of Correlations

We investigate a microscopic model based on the pair approximation, for the dynamical properties of the photo-induced high-spin state in spin-crossover solids at low temperature. The model uses the Ising-like hamiltonian and combines longand short-range interactions. The stochastic treatment of the latter provides a set of two coupled differential equations for the macroscopic shortand long-ran...

Glass-like recovery of antiferromagnetic spin ordering in a photo-excited manganite Pr0.7Ca0.3MnO3

Electronic orderings of charges, orbitals and spins are observed in many strongly correlated electron materials, and revealing their dynamics is a critical step toward undertsanding the underlying physics of important emergent phenomena. Here we use time-resolved resonant soft x-ray scattering spectroscopy to probe the dynamics of antiferromagnetic spin ordering in the manganite Pr₀.₇Ca₀.₃MnO₃ ...

Photo-crystallography: from the structure towards the electron density of metastable states

A photo-crystallographic study of Fe(btr)2(NCS)2.H2O was performed in order to describe the modification of structures and charge densities on going from the ground low spin (LS) state to the metastable high spin (HS) state during the LIESST phenomenon at 15K. Related photo-magnetic and spectroscopic measurements are also described. We show that at 15K, the thermally quenched and photo-induced ...

Fabrication of Nanofiltration Membrane from Polysulfone Ultrafiltration Membrane Via Photo olymerization

UV-induced grafting technique was used as a flexible method for surface modification of Polysulfone (PSf) ultrafiltration (UF) membranes in order to prepare hydrophilic nanofiltration (NF) membranes. Flat sheet Polysulfone (PSf) ultrafiltration membranes were prepared via phase inversion method. N-methylene-2-pyrrolidone (NMP) and polyethylene glycol (PEG) of three different molecular weights (...

Pressure induced separation of phase-transition-triggered-abrupt vs. gradual components of spin crossover.

The application of pressure on [Co(II)(dpzca)2], which at ambient pressure undergoes abrupt spin crossover (SCO) with thermal hysteresis, gives unique insights into SCO. It reversibly separates the crystallographic phase transition (I41/a↔P21/c) and associated abrupt SCO from the underlying gradual SCO, as shown by detailed room temperature (RT) X-ray crystallography and temperature dependent m...
