摘要：

We measured the magnetization of CeRu2Al10 single crystal with a good quality along all the crystal axes and disccused the results from the standpoint of the antiferromagnetic(AFM) order recently proposed by Khalyavin et al. x along all the crystal axes shows a clear thermally activated temperature dependence below T-0. These results are dificult to be explained at least by a simple AFM order. We propose the possible existence of a spin singlet nature below T-0 even when the AFM order takes place.
