Abstract

As Cu2+ ions in Cu3V2O7(OH)(2). 2H(2)O form two-dimensional deformed kagome lattice structure in the ab plane, frustration is expected. To clarify the magnetic properties of this system, we performed X-band ESR measurement and high-field ESR measurements up to 16T. The ESR signal disappeared below 5 K in X-band ESR measurement and the ESR absorption line showed clear shift below 4.2K in our high-field ESR measurement at 80GHz. Although no long-range order is expected around 4K from the result of the specific heat measurement, our frequency-dependent measurement at 1.8 K showed the existence of the internal field in Cu3V2O7(OH)(2). 2H(2)O. The results of the temperature dependences of the resonance field and the linewidth are also presentedand discussed in connection with other kagome substances. (C) 2001 Elsevier Science B.V.
