Paper Abstract

We describe the spectrometers we developed for CW and pulsed high frequency ESR spectroscopy. The characteristics of the sources are detailed. Our aim was twofold i) to reach the highest possible frequency ii) to devise frequency step-tunable spectrometers. The obvious interests to develop high frequency/high magnetic field ESR spectrometers lie in the possibility to study paramagnetic systems with large zero field splittings, to take advan- tage of an increase in g-factor resolution and to observe time dependent phenomena in a new time scale. There are less obvious advantages like spin polarizaation effects or the study of linewidth frequency dependence. We present mainly results obtained with the CW spectrometer which is in a more advanced development stage than the pulse spectrometer.
