- Abstract summary: We propose a pump-probe spin resonance spectroscopy approach, based on microwave pump fields and electron probes.
We investigate how quantum spin systems couple to electron matter waves through their magnetic moments.
This could enable state-selective observation of spin dynamics on the nanoscale and indirect measurement of the environment of the examined spin systems.

- Abstract: Coherent spin resonance methods, such as nuclear magnetic resonance and
electron spin resonance spectroscopy, have led to spectrally highly sensitive,
non-invasive quantum imaging techniques. Here, we propose a pump-probe spin
resonance spectroscopy approach, designed for electron microscopy, based on
microwave pump fields and electron probes. We investigate how quantum spin
systems couple to electron matter waves through their magnetic moments and how
the resulting phase shifts can be utilized to gain information about the states
and dynamics of these systems. Notably, state-of-the-art transmission electron
microscopy provides the means to detect phase shifts almost as small as that
due to a single electron spin. This could enable state-selective observation of
spin dynamics on the nanoscale and indirect measurement of the environment of
the examined spin systems, providing information, for example, on the atomic
structure, local chemical composition and neighboring spins.
