TL;DR: In this paper, a new magnetic equation of state for liquid /sup 3/He is derived from a model for the polarization dependence of the Landau parameters, which is constrained by general thermodynamic relationships and microscopic symmetries.
Abstract: A new magnetic equation of state for liquid /sup 3/He is derived. This is obtained from a model for the polarization dependence of the Landau parameters. The parameters of the model are constrained by general thermodynamic relationships and microscopic symmetries. It is shown that the nonlinear field splitting of the A phase in liquid /sup 3/He is consistent with this model. We propose that liquid /sup 3/He can be viewed as nearly metamagnetic.

TL;DR: The authors' sound velocity, sound attenuation, and ac magnetic susceptibility measurements all show strong anomalies near the critical magnetic field of this metamagnetic transition in CeRu 2.
Abstract: We present experiments and model calculations concerning the metamagnetic transition in ${\mathrm{CeRu}}_{2}$${\mathrm{Si}}_{2}$. Our sound velocity, sound attenuation (down to 60 mK), and ac magnetic susceptibility measurements (down to 20 mK) all show strong anomalies near the critical magnetic field of this transition. We can account for this behavior using scaling arguments and a more microscopic model based on the Kondo volume collapse.
