Highly sensitive magnetic detection of electron spin resonance (ESR) using a microcantilever is presented. By combining a modulation technique with the use of a piezoresistive cantilever, we successfully observed ESR signals of a tiny single crystal (mass<1 μg) of Co Tutton salt, Co (NH4) 2 (SO4) 2 6 H2 O, in the frequency region of 80-240 GHz. The achieved spin sensitivity was ∼ 109 spins/G at 4.5 K, providing promising applications to high-resolution and high-sensitivity terahertz ESR.
