| Popis: | Trabajo presentado a la V European School on Molecular Nanoscience (ESMolNa) celebrada en Cuenca (España) del 28 de octubre al 2 de noviembre de 2012. An excellent molecule-based cryogenic magnetic refrigerant, gadolinium acetate tetrahydrate, is here used to decorate selected portions of silicon substrate. By quantitative magnetic force microscopy for a variable applied magnetic field near liquid-helium temperature, the molecules are demonstrated to hold their magnetic properties intact, and therefore their cooling functionality, after their deposition. These results represent a step forward towards the realization of a molecule-based micro-refrigerating device at very low temperatures. This work was supported by the Spanish MINECO through grants CSD2007-00010, MAT2011-24284 and MAT2012-38318, by a CSIC JAE-technician fellowship (to P.G.-M.) and by an EU Marie Curie IEF (PIEF-GA-2011-299356, to G.L.). |
