Abstract

The band metamagnet UCoAl was found to exhibit non-Fermi liquid scaling of electrical resistivity. In this contribution, we describe resistivity data on UCoAl single crystal obtained under extreme conditions. We demonstrate that a bT5/3 term extends to temperatures below 0.5 K and that very high pressure (>5 GPa) is necessary to drive UCoAl to the Fermi liquid regime.
