Acoustic emissions from spin crossover complexes.

J Mater Chem C Mater
Listening to the acoustic noise emitted by molecular spin crossover materials reveals both reversible and irreversible microstructural phenomena associated with the spin transition, providing a simple tool to detect structural fatigability.

Coupled spin cross-over and ferroelasticity: revisiting the prototype [Fe(ptz)6](BF4)2 material

Advances in Physics: X, 2023
Spin-crossover (SCO) materials exhibit thermal conversion from low to high-spin states. We review different models developed to describe this entropy-driven process and the occurrence of cooperative conversions resulting from elastic interactions.

Spin-state-dependent electrical conductivity in single-walled carbon nanotubes encapsulating spin-crossover molecules

Nature Communications, 2021
Spin-crossover molecules can change their spin-state under a variety of stimuli making them ideal sensors; however, they are typically insulating and unstable.

Controlling the strong light-matter coupling in metal-dielectric optical resonators using spin-crossover molecules [PDF]

EPJ Web of Conferences, 2023
We report the observation of (ultra)strong light-matter coupling, in the UV spectral region, between optical modes of a metal/dielectric bilayer nanocavity and the electronic excitations of spin-crossover (SCO) molecules.

Ultrafast spin crossover in a single crystal [PDF]

EPJ Web of Conferences, 2019
Femtosecond spectroscopy and electron diffraction are used to characterize spin crossover in single crystal iron(II)-tris(bipyridine)-bis(hexafluorophosphate). The high-spin lifetime is reduced compared to in solution.

Continuous control of classical-quantum crossover by external high pressure in the coupled chain compound CsCuCl3

Nature Communications, 2021
In real materials, a spin quantum number assumes a fixed value, which makes it challenging to realize a crossover between quantum and classical spin regimes.

Variability of the Conductance Changes Associated with the Change in the Spin State in Molecular Spin Crossover Complexes

Magnetochemistry, 2023
Here, we examine the conductance changes associated with the change in spin state in a variety of different structures, using the example of the spin crossover complex [Fe(H2B(pz)2)2(bipy)] (pz = (pyrazol-1-yl)-borate and bipy = 2,2′-bipyridine) and [Fe ...

Metal Substitution Effect on a Three-Dimensional Cyanido-Bridged Fe Spin-Crossover Network

Inorganics, 2017
We report the CoII-substitution effect on a cyanido-bridged three-dimensional FeII spin-crossover network, Fe2[Nb(CN)8](4-pyridinealdoxime)8·2H2O. A series of iron–cobalt octacyanidoniobate, (FexCo1−x)2[Nb(CN)8](4-pyridinealdoxime)8·zH2O, was prepared ...

Spin state switching in iron coordination compounds

Beilstein Journal of Organic Chemistry, 2013
The article deals with coordination compounds of iron(II) that may exhibit thermally induced spin transition, known as spin crossover, depending on the nature of the coordinating ligand sphere. Spin transition in such compounds also occurs under pressure

Anomalous Pressure Effects on the Electrical Conductivity of the Spin Crossover Complex [Fe(pyrazine){Au(CN)₂}₂]

Magnetochemistry, 2020
We studied the spin-state dependence of the electrical conductivity of two nanocrystalline powder samples of the spin crossover complex [Fe(pyrazine){Au(CN)2}2].
