Abstract [en]

The thermal and electrical conductivities of nickel have been studied under hydrostatic pressures up to 1.6 GPa at room temperature. Allowing for the pressure dependence of the lattice thermal conductivity, the electronic Lorentz function increases with pressure with an approximate pressure coefficient of 2 × 10-2 GPa-1. This is in strong disagreement with the standard Bloch-Grüneisen theory which predicts a volume independent Lorentz number
