Abstract

A novel technique of high-frequency electron spin resonance (ESR) in a pulsed magnetic field is presented. Our technique is based on the magnetic detection of a magnetization change associated with the ESR absorption using a microcantilever. We successfully observed ESR signals of a microcrystal (mass∼1 μg) in the millimeter-wave region up to 130 GHz in pulsed magnetic fields of up to 2.4 T. This result corresponds to the spin sensitivity of ∼ 1011 spins/G, which is four orders of magnitude better than that of conventional transmission-type ESR techniques.
