Abstract

The electron spin resonance (ESR) at low frequency (0.6-3 GHz) and at low temperature (∼0.5 K) was performed for the single molecular magnet V15. Non-linear field dependence of resonance at the lowest temperature implies the existence of the zero-field gap. The angle dependence of resonance field has strong anisotropy. We directly estimate the zero-field energy gap of 30 mK and analyze the energy levels using the model with Dzyaloshinskii-Moriya interaction.
