Photo-induced magnetic bistability in a controlled assembly of anisotropic coordination nanoparticles

摘要

Anisotropic coordination nanoparticles of the photomagnetic network Cs~Ⅰ2Cu~_2Ⅱ_7IMo~Ⅳ(CN)_8]_4 are obtained through a surfactant-free high-yield synthetic procedure in water. These particles are organised as Langmuir-Blodgett films with a preferential orientation of the nano-objects within the film that exhibit a magnetic bistability below 20 K with a very large coercivity due to an efficient photo-transformation.
