Abstract:
Magnetic molecules are fascinating mesoscopic systems with high chemical modularity, which permits changing their structural and physical functionalities at will. Therefore, these materials are an ideal playground for the study of nanoscale magnetic phenomena. Besides, they are very attractive for the implementation of cutting-edge applications, such as quantum technologies and low temperature magnetic refrigeration. 
In this talk several research activities in the field will be presented, with special attention on molecular-based materials for magnetic refrigeration applications, and on high-sensitive micro-electro-mechanical devices for their advanced magnetic characterization. These sensors, upon minor modifications, can be also employed as host chips for molecular micro-refrigerators, that could replace the complex and bulky refrigerators that are currently used. It is hoped that in a not-too-distant future such microchips can be used as cooling platforms in all kinds of experiments that require temperatures close to absolute zero, e.g., for gamma and X-ray detection in astronomy, materials science, quantum computing or safety instrumentation.
