Original Abstract

With dimensions close to a nanometer and the ability to store one bit of information, molecules called Single-Molecule Magnets (SMMs) give a possibility to move the data storage technology forward. For the investigation of SMMs, spectroscopic techniques, such as Electron Paramagnetic Resonance (EPR), are essential due to their ability to probe molecular and electronic properties directly. However, because of systems with large zero-field splitting, Fourier Transform Infrared (FTIR) spectroscopy in high magnetic field is needed in order to access fundamental transitions in SMMs. We propose FTIR spectroscopy in high magnetic fields as a very important tool in the characterization of SMMs. This method allows studying EPR of SMMs with very large zero-field splitting, mainly based on transition metal complexes [1] or lanthanides [2] that cannot be studied by common EPR systems since they do not provide experimental access to the magnetic resonance transitions. It also presents an ideal experimental technique that can probe band structure and elucidate electronic properties of novel 2D materials, such as graphene [3]. The method of FTIR spectroscopy in high magnetic fields will be mediated by compact FTIR magneto-optical setup built at CEITEC, which is basically FTIR spectrometer connected to 16 Tesla cryogen-free superconductive magnet.
