Abstract
Possible quantum critical behaviour in the (Cr84Re16)100−yVy alloy system, with 0 ≤ y < 14, was investigated using electrical resistivity (ρ), Seebeck coefficient (S), magnetic susceptibility (χ), Hall coefficient (RH), and specific heat (Cp) measurements as a function of temperature (T). Characteristics typically associated with a quantum critical point (QCP) can be observed in the low temperature behaviour of ρ(y), RH(y), χ(y), and γ(y); where γ is the Sommerfeld coefficient determined from least square fits to the low temperature specific heat measurements. Present results provide evidence of the existence of a putative QCP at a critical concentration of yc ≈ 10.5 for the (Cr84Re16)100−yVy alloy system.
