Abstract
High quality single crystal CrAs was grown by Sn flux method. The results of magnetic susceptibility and electrical resistivity are reported in a temperature range of 2 to 800 K. At low temperatures, a T 2 dependence of resistivity is observed showing a Fermi-liquid behavior. The Kadowaki-Woods ratio is found to be 1×10−5 μΩ cm mol2 K2 mJ−2, which fits well to the universal value for many correlated electron systems. At about 270 K, a clear magnetic transition is observed with sharp changes of resistivity and susceptibility. Above 270 K, a linear-temperature dependence of the magnetic susceptibility is observed up to 700 K, which resembles the T-dependent magnetic susceptibility of parents of iron-pnictides superconductors.
