摘要：
The boundaries between the antiferromagnetic (AF) and spin-flop (SE) phases in solid solutions of the low anisotropy antiferromagnets Rb2Fe1-xInxCl5 . H2O (x = 0.00, 0.10) have been studied by means of neutron diffraction experiments. The experiments show that the presence of In impurities can originate, at the AF-SF region, a coherent gradual rotation of the Neel vector from the a direction to the c direction according to theoretical predictions.
