Possible quantum critical behaviour in the (Cr₈₄Re ₁₆)_100-yV_y alloy system

Possible quantum critical behaviour in the (Cr₈₄Re ₁₆)_100-yV_y alloy system, with 0 y 14, was investigated using electrical resistivity (ρ), Seebeck coefficient (S), magnetic susceptibility (χ), Hall coefficient (R_H), and specific heat (C_p) 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), R_H(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 y_c ≈ 10.5 for the (Cr ₈₄Re₁₆)_100-yV_y alloy system.
