Broadband electron paramagnetic resonance of single-molecule magnets at millikelvin temperatures. — •Konstantin Petukhov¹, Klaus Gieb¹, Thorsten Glaser², Wolfgang Hansen³, and Paul Müller¹ — ¹Institut für Physik der Kondensierten Materie, Universität Erlangen-Nürnberg — ²Lehrstuhl für Anorganische Chemie I, Universität Bielefeld — ³Institut für Angewandte Physik, Universität Hamburg

We present a technique which combines Hall-bar magnetometry of single-molecule magnets (SMMs) with broadband microwave absorption measurements. This electron paramagnetic resonance-like spectroscopy can be performed at millikelvin temperatures and enables the use of short-pulsed microwave radiation. Thus, the spin dynamics of SMMs can be studied. We present measurements on novel Mn₆Mn and Mn₆Cr single-molecule magnets.
