Coherent spin resonance methods such as nuclear magnetic resonance (NMR) and electron spin resonance (ESR) spectroscopy have led to spectrally highly sensitive, non-invasive quantum imaging techniques with groundbreaking applications in fields such as medicine, biology, and physics. Meanwhile, transmission electron microscopy (TEM) offers detailed investigations with sub-atomic resolution, but often inflicts significant radiation damage. Here we exploit synergies and report on an integration of ESR spectroscopy in a TEM. Our miniaturized ESR setup on a standard TEM sample holder leverages the strong magnetic field of the TEM polepiece to align and energetically separate spin states. This integration will facilitate in-situ studies of spin systems and their dynamics, quantum materials, radicals, electrochemical reactions, and radiation damage - properties previously mainly invisible to electron microscopic tools. Moreover, this development marks a significant technological advancement toward microwave-controlled quantum spin studies with a highly controlled electron probe at the nanoscale.
