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.

MOOS探索有机半导体中磁光效应的自旋放大：研究新材料、机制及其在先进光磁场传感器中的应用。磁光效应是由偏振光与磁场中的材料相互作用产生的。这种技术的应用范围从通信中的光控制到可以监测大脑和心脏活动的高灵敏度磁场传感器，无论是现在的还是正在出现的。磁光学的未来应用需要在性能和可加工性方面的逐步改变，这需要在磁性晶体无机材料之外的方法上的逐步改变。英国（Evans）、法国（Favereau）和德国（Richert）早期职业研究人员之间的国际合作，使建立一个新的磁光有机半导体领域的研究成为可能，他们是先进材料设计、光谱学和薄膜器件互补领域的专家。MOOS通过在固态薄膜中具有稳定自由基的激发态动力学的分子工程，为磁光半导体提供了新的光和自旋物理学。MOOS将展示有机材料与偏振光的自旋增强相互作用，使磁场检测极限比目前的技术水平低几个数量级。
