摘要
We have investigated the possible occurrence of magnetic Bloch oscillations in CoCl2 . 2D(2)O. We were unable to observe these oscillations at 20.0 K, just above T-N. In an attempt to explain this result, we studied spin waves in the a*-c* plane in order to estimate the effect of the interchain couplings. The values we obtain for the coupling parameters are in reasonable agreement with the previous studies in the b*-c* plane. (C) 2000 Elsevier Science B.V. All rights reserved.
