  1. For each compound the tuning parameter (uniaxial strain ϵ or magnetic field H) and the associated critical values are indicated. The behavior (peak or no peak) across the critical tuning of the temperature-independent term in resistivity ρ0, Sommerfeld coefficient γ, and electron–electron scattering coefficient A (see text) is indicated. Finally, the observed resistivity behavior (Fermi liquid or non-Fermi liquid) at the critical tuning and lowest measured temperature is given.
