Journal ArticleDOI

TL;DR: In this paper, a combination of scanning tunnelling microscopy measurements and ab initio calculations allows discriminating unambiguously between two spin states by local vibrational spectroscopy, and a single layer of spin cross-over molecules in contact with a metallic surface displays light-induced collective processes between two ordered mixed spin-state phases with two distinct timescale dynamics.
Journal ArticleDOI
Benzoxazole-Based Heterometallic Dodecanuclear Complex [(Dy4Cu8II)-Cu-III] with Single-Molecule-Magnet Behavior
Olga Iasco,Ghenadie Novitchi,Ghenadie Novitchi,Erwann Jeanneau,Wolfgang Wernsdorfer,Dominique Luneau +5 more
TL;DR: Three Cu-Ln (Ln = Dy, Gd, Y) dodecanuclear clusters assembled by a novel ligand of the benzoxazole type are reported, indicating single-molecule-magnet behavior.
Journal ArticleDOI
FeII(pap-5NO2)2 and FeII(qsal-5NO2)2 Schiff-Base Spin-Crossover Complexes: A Rare Example with Photomagnetism and Room-Temperature Bistability
Olga Iasco,Eric Rivière,Régis Guillot,Marylise Buron-Le Cointe,Jean-Francois Meunier,Azzedine Bousseksou,Marie-Laure Boillot +6 more
TL;DR: The Mössbauer analysis supports a description of these compounds as Fe(II) Schiff-base complexes and the occurrence of a metal-centered spin crossover process.
Journal ArticleDOI
Lanthanide Triangles Sandwiched by Tetranuclear Copper Complexes Afford a Family of Hendecanuclear Heterometallic Complexes [Ln III 3 Cu II 8 ] (Ln = La–Lu): Synthesis and Magnetostructural Studies
TL;DR: A comparative analysis of the magnetic data for the lanthanum (1) and lutetium (11) compounds shows the presence of ferromagnetic and antiferromagnetic interactions within the μ4-oxo {Cu4} moieties.
Journal ArticleDOI
Temperature-, Light-, and Soft X-ray-Induced Spin Crossover in a Single Layer of FeII-Pyrazolylborate Molecules in Direct Contact with Gold

TL;DR: In this paper, the spin crossover from the low spin state to the high spin state can also be induced by X-ray and light excitations, and it is shown that the spin-crossover transition can be thermally induced from the high-spin state to a mixed spin state phase containing one-third of high spin-state and two-thirds of low-spin-state molecules.
