Abstract

Electrical resistivity, Hall effect, specific heat, and neutron diffraction measurements are used to investigate magnetic and quantum critical behavior in a commensurate spin-density-wave (CSDW) antiferromagnetic (Cr86 Ru14)1-x Vx alloy system. The x-T magnetic phase diagram obtained from the measurements depicts a critical point, occuring at T=0 K for a critical V concentration xc =0.104. This point is classified as a CSDW-type quantum critical point using recently suggested methods for classification of quantum critical points from Hall measurements.
