From measurements of magnetic properties of CeNiSn, it has been found
that a kink appears at about 3 T in the magnetization curve at 4.5 K w
hile there is no kink at 15 K. Moreover, magnetic field can shift the
peak of magnetic susceptibility to lower temperature, which gives furt
her evidence of the existence of antiferromagnetic correlations. This
paper also discusses the role that antiferromagnetic correlations play
.
