Effects of the Dzyaloshinskii-Moriya interaction on low energy magnetic excitations in copper benzoate
J. Z. Zhao, X. Q. Wang, T. Xiang +2
We have investigated the physical effects of the Dzyaloshinskii-Moriya (DM) interaction in copper benzoate. In the low field limit, the spin gap is found to vary as $H^{2/3}\ln ^{1…
