概要

• 論文の詳細を見る

• Heat capacity and susceptibility measurements are performed down to 70 mK under magnetic fields in the Haldane-gap antiferromagnet (CH_3)_4NNi(NO_2)_3(TMNIN). We have observed no magnetic long range order within our experimental range of the temperature down to 70 mK and the magnetic field up to 7 T. The heat capacity reflects the field dependence of the energy gap and show a broad anomaly above a critical field H_c, which has been also observed in NENP. In the adiabatic magnetization measurement, the spin temperature shows a minimum around H_c. These results are interpreted as increasing of the energy gap above H_c which may suppress the expected long-range-ordering.
