Wilson ratio

The strength of interaction can also be provided through the Wilson ratio [60]... 

With respect to the magnetic and thermal Gruneisen parameters ilj. (sect. 4.4) it has recently been shown that ilg > ilj for transition-metal compounds with strong Stoner enhancement, (Kaiser and Fulde 1988). Since the Sommerfeld-Wilson ratio,... 

Many features of the data may be conveniently discussed in terms of theoretical descriptions based on the Fermi-liquid model. We shall start by considering the shape of the low-temperature response, for which the analytic function given by Kuramoto and Miiller-Hartmann (1985) is useful. This is followed by a discussion of some more general aspects arising from a consideration of the Wilson ratio (Wilson 1975, Lustfeld and Bringer 1978).

Fujishima et al. [95] used optical-conductivity spectra to monitor the increase in effective mass of the electrons with La concentration. Kumagai et al. [96] measured the electronic specific heat y at low temperatures and compared it to the magnetic susceptibility x obtained by Tokura et al. [97] on the same samples see Fig. 21. The Wilson ratio //y remained nearly constant over the entire range of x, which indicates that the divergence of y and x on... 

Ba3Co206(C03)o.7 was studied by Ba NMR. It was reported that marginally itinerant electrons possess large entropy and low-lying excitations with a Wilson ratio Rw=H6.
