Perhaps the most sensitive test for the presence of paramagnons is the predicted large T2 term in the resistivity if this occurs without a correspondingly large increase in y then paramagnons rather than Baber scattering are indicated. Figure 3.20 (from Tari and Coles 1971) shows the behaviour of the constant A in Pd-Ni, where... 

The T2 term in the resistivity p of metallic V203 above 20kbar, first observed by McWhan and Rice (1969), is shown in Fig. 6.7. It will be noticed that there is some tendency for p to saturate above 300 K as for Landau-Baber scattering with a low degeneracy temperature (Chapter 2). 

Cohen and Thompson (1968) considered that electron-electron (Landau-Baber) scattering (see Chapter 2, Section 6) is also important, because the Fermi energy is small compared with that of a normal metal. In the liquid, because the... 

The relationship between the T2 coefficient A and the specific heat y was demonstrated by Kadowaki and Woods (1986), see also fig. 2.3. For a number of Ce and U compounds with high y values, a universal ratio A/y2 = 1.0 X 10-5 p, 2 cm (mol K/mJ)2 was found. This fact may suggest that both the electrical resistivity and the specific heat are renormalized, due to many-body correlations, in a similar way in the sense of argumentation sketched by Yarma (1985). In d transition metals, where the correlation enhancement does not represent a major portion of y, the A T2 resistivity term can be attributed to electron-electron scattering (Baber 1937), the value of A/y2 being more than one order of magnitude lower (Rice 1968).
