- 論文の詳細を見る
Antiferromagnetic resonance experiment was performed on a single crystal of CoCl_26H_2O in the frequency range of 9.5 to 47 kMc/sec at liquid helium temperature. The result can be understood by the theory of antiferromagnetic resonance developed by Nagamiya and Yosida and also by Ubbink et al., except for certain systematic deviations from the theory. These deviations can be removed by introducing a large anisotropic exchange interaction of the symmetric tensor form in place of the ordinary small anisotropy energy. Thus, the effective fields acting on sublattice magnetizations, M^+ and M^-, are assumed to be of the form H_θ^±=-AM^〓-TM^±A'M^〓-T'M^±, where A and T are the isotropic molecular field constants and A' and T' are newly introduced anisotropic molecular field tensors.
