Abstract

Azurite, Cu₃(OH)₂(CO₃)₂ is a candidate of the model substance for diamond chain with antiferromagnetic interaction. The millimeter and submillimeter wave ESR measurements of Cu ₃(OH)₂(CO₃)₂ single crystal have been performed in the frequency region from 50 to 360 GHz and in the temperature region from 1.8 to 90 K. As the line width of ESR extends up to 3 T and it is impossible to observe by a conventional X-band ESR, the high field ESR measurement turned out to be essential. The g-shift was observed below 20 K, which corresponds to a peak of the magnetic susceptibility. Therefore, the development of the short range order may be the origin of the resonance shifts.
