Quantum critical phase in BaVS3
Abstract
We study the high-pressure metallic phase of high-purity single crystals of BaVS3 by measuring the temperature, pressure, and magnetic field dependence of the resistivity. Above the critical pressure of p cr=1.97GPa an extended non-Fermi liquid p-T regime emerges with resistivity exponent 1.5 n<2, crossing over to a FL only around p=2.7GPa. A hysteretic feature indicates that close to the insulator--metal boundary, the system is magnetically ordered. Our findings reveal a close analogy between the extended partially ordered NFL state of non-conventional itinerant magnets and the corresponding state of BaVS$3
