Journal Article
Towards spin crossover applications
TL;DR: In this article, the potential for the application of the spin crossover (SCO) phenomenon in various domains, such as molecular electronics, data storage, display devices, is reviewed, and several requirements must be fulfilled before any use in a genuine device becomes feasible.
Journal ArticleDOI
Structural, Magnetic, and Photomagnetic Studies of a Mononuclear Iron(II) Derivative Exhibiting an Exceptionally Abrupt Spin Transition. Light-Induced Thermal Hysteresis Phenomenon.

TL;DR: The new spin-crossover compound Fe(PM- biA)(2)(NCS)(2) with PM-BiA = N-(2-pyridylmethylene)aminobiphenyl has been synthesized and the determination of the intermolecular contacts in the LS and HS forms has revealed a two-dimensional structural character.
Journal Article
Structural aspects of spin crossover. Example of the [FeIILn(NCS)2] complexes
TL;DR: In this paper, structural modifications due to spin crossover are first estimated, these include the expansion and the distortion of the FeN 6 octahedron, the isotropic and the anisotropic changes of the unit cell.
Journal ArticleDOI
Photomagnetism of iron(II) spin crossover complexes—the T(LIESST) approach
TL;DR: In this paper, the T(LIESST) procedure is used to measure the limit temperature above which a photomagnetic effect in a material is erased by warming the material from 10 K at a rate of 0.3 K min−1.
Journal ArticleDOI
A guideline to the design of molecular-based materials with long-lived photomagnetic lifetimes.

TL;DR: A correlation between the nature of the coordination sphere of the metal and the photomagnetic lifetime can be drawn and this result clearly opens the way towards room-temperature photonic materials, based on the spin-crossover phenomenon, which will be of great interest for future communication devices.
