We show that a very broad frequency range, from 0.5 to 40 GHz, becomes accessible with a high frequency accuracy of less than 1 MHz at low temperatures down to 1.6 K and in fields up to 1.4 T. This allows an accurate inspection of the ESR absorption position in the frequency domain, in contrast to the more common observation in the field domain. We demonstrate the applicability of frequency-swept ESR on Cr3+ atoms in ruby as well as on organic radicals of the Nitronyl-nitroxi","authors_text":"C. Clauss, D. Bothner, D. Koelle, L. Bogani, M.
