Atomically tweaking spin-crossover cooperativity to augment molecular memory density [PDF]

Nature Communications
Spin-crossover complexes are promising candidates for molecular bits owing to their magnetic bistability. However, it’s a formidable challenge to turn densely packed spin-crossover molecules into high-density bits due to cooperative switching dynamics ...

The Influence of the Substrate on the Functionality of Spin Crossover Molecular Materials [PDF]

Molecules, 2023
Spin crossover complexes are a route toward designing molecular devices with a facile readout due to the change in conductance that accompanies the change in spin state.

Cooperative spin crossover leading to bistable and multi-inert system states in an iron(III) complex [PDF]

Nature Communications
Cooperativity among spin centres has long been the royal road in spin crossover (SCO) research to impose magnetic bistability in terms of thermal hysteresis.

Elastocaloric, barocaloric and magnetocaloric effects in spin crossover polymer composite films [PDF]

Nature Communications
Giant barocaloric effects were recently reported for spin-crossover materials. The volume change in these materials suggests that the transition can be influenced by uniaxial stress, and give rise to giant elastocaloric properties.

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 ...
