We propose to establish Plasmon-enhanced Terahertz Electron Paramagnetic Resonance spectroscopy and scanning microscopy as a unique Electron Paramagnetic Resonance (EPR) platform for high-sensitivity local analysis of paramagnetic organic and inorganic species and materials. Here, we will deliver novel hardware and infrastructure providing ground-breaking innovation in the magnetic sensing and imaging. The platform is conceptually based on incorporating THz plasmonic antennas onto surfaces (spectroscopy) and scanning probe tips (microscopy), resulting in a strong, local enhancement (about two orders of magnitude) of the magnetic sensing field.
Extending to the THz region enables effective utilization of plasmonic structures resulting in a radical improvement of EPR sensitivity (about four orders of magnitude) and spatial resolution going beyond the diffraction limit, and thus introduce a scanning probe microscopic regime into this field. This will make it possible to map the sample over its area and so to localize its properties with unprecedented resolution (below 1 micrometre). Such a significant enhancement of the EPR performance will open new ways in magnetic sensing technologies enabling for instance to study in situ functional centres in a wide variety of materials, and, generally, set a new direction in the development of the EPR-employing industry.
EPR finds its applications in many scientific areas covering chemistry, biology, medicine, materials science, physics, etc. Hence, introducing this new method would have a profound impact on scientific, technological and societal stakeholders in many research and industrial communities.
