NEXT NanoMagnets for quantum Sensing and Data SToragE

The present research project, funded by the National Institute for Nuclear Physics (INFN), aims at performing studies on the characterization of known MNMs as high-sensitivity quantum sensors, as well as synthesizing and characterizing new SIMs for potential future applications as high-density memory storage systems.

The objectives of the project are: (i) study of the Mn12-tbu system, partly investigated in the previous INFN-CSN5 project NAMASSTE, at first (other MNMs can be later considered) as a quantum sensor for impinging radiation or for a magnetic field B, transverse with respect to its c easy anisotropy axis;

(ii) search for new MNMs suitable for data storage, studying Ln-based SIMs with two units coupled by a bias interaction and high-barrier SIMs resistant to ambient conditions, to determine the sources of magnetization relaxation. Theoretical studies will support the experimental phases by modelling the effects of the external perturbations on the measured parameters.
