We present the structure and anisotropic magnetic and electrical transport properties on the flux-grown PrAlGe single crystal, a recently proposed magnetic Weyl semimetal candidate. From the powder and single-crystal x-ray diffraction analysis, the grown crystal is revealed to crystallize in tetragonal LaPtSi-type structure with space group of I4(1)md. The PrAlGe exhibits strong Ising-type magnetic anisotropy with ferromagnetic moments approximate to 2.32(B)/Pr along easy c-axis below transition temperature T-c approximate to 15 K. Accordingly, anomalous Hall effect (AHE) is observed for field (H) along c axis in contrast to a axis, and large anomalous Hall conductivity value reaches up to approximate to 680 (-1) cm(-1) close to the theoretical expected value based on intrinsic Berry-curvature mechanism. Moreover, the linear scaling behaviors between the anomalous Hall resistivity and longitudinal resistivity also support the intrinsic Karplus-Luttinger mechanism as a dominant role on the observed AHE rather than extrinsic scattering mechanism.
