Evolution of cooperativity in the spin transition of an iron(II) complex on a graphite surface
Nature Communications, 2018 Spin-crossover molecules offer a potential route towards molecular spintronics, but retaining the bistability of the spin state upon surface deposition is challenging.

The foundation of modern spin-crossover [PDF]
Chemical Communications, 2013 The first explanation of spin-crossover in iron( ii ) complexes was published in Chem. Commun. in 1966. This has led to nearly 50 years of research in coordination chemistry, crystal engineering, solid state chemistry and physics, and nanoscience.

Pressure and Temperature Sensors Using Two Spin Crossover Materials
Sensors, 2016 The possibility of a new design concept for dual spin crossover based sensors for concomitant detection of both temperature and pressure is presented. It is conjectured from numerical results obtained by mean field approximation applied to a Ising-like ...

A μSR study of the spin-crossover
Journal of Physics and Chemistry of Solids, 2004 The spin-crossover phenomenon is a cooperative low-spin to high-spin transition which can be initiated using temperature or light-irradiation. We have used muon-spin relaxation (μSR) to study this effect in Fe(PM-PEA)2(NCS)2 and Fe(PMAzA)2(NCS)2. We find Gaussian or exponential muon relaxation in the high-spin phase for the two compounds, reflecting ...

Molecular-scale dynamics of light-induced spin cross-over in a two-dimensional layer
Nature Communications, 2016 Spin crossover molecules may find applications in ultimately small magnetic devices, given the sensitivity of their spin-states to external stimuli. Here, the authors show a light-induced transition between two ordered dynamic phases in two-dimensional ...

Spin-State Ice in Elastically Frustrated Spin-Crossover Materials [PDF]
Journal of the American Chemical Society, 2019 Spin crossover materials contain metal ions that can access two spin-states: one low-spin (LS), the other high-spin (HS). We propose that frustrated elastic interactions can give rise to spin-state ices -- phases of matter without long-range order, characterized by a local constraint or `ice rule'. The low-energy physics of spin-state ices is described

Dynamics of Spin Crossover Molecular Complexes
Nanomaterials, 2022 We review the current understanding of the time scale and mechanisms associated with the change in spin state in transition metal-based spin crossover (SCO) molecular complexes. Most time resolved experiments, performed by optical techniques, rely on the intrinsic light-induced switching properties of this class of materials.

Spin-state smectics in spin crossover materials [PDF]
Journal of Applied Physics, 2021 We show that a simple two-dimensional model of spin crossover materials gives rise to spin-state smectic phases where the pattern of high-spin (HS) and low-spin (LS) metal centers spontaneously breaks rotational symmetry and translational symmetry in one direction only. The spin-state smectics are distinct thermodynamic phases and give rise to plateaus
