MOOS explores spin amplification of magneto-optical effects in organic semiconductors: studying new materials, mechanisms and applications in advanced optical magnetic field sensors.Magneto-optical effects arise from the interaction of polarised light with materials in a magnetic field. This has present and still emerging applications that span from light control in communications to high sensitivity magnetic field sensors that could monitor brain and heart activity. Future applications of magneto-optics require step changes in performance and processability, which demands a step change in approach outside the norm of magnetic, crystalline inorganic materials.Research towards establishing a new field of magneto-optical organic semiconductors is enabled by an international collaboration between UK (Evans), France (Favereau) and Germany (Richert) early-career researchers, who are experts in complementary fields of advanced materials design, spectroscopy and thin-film devices.MOOS advances new photo- and spin physics for magneto-optical semiconductors by molecular engineering of excited state dynamics with stable radicals in solid-state films. MOOS will demonstrate spin enhanced interactions of organic materials with polarised light to enable orders of magnitude lower magnetic field detection limit than the current state of the art.
