Transport, magnetic, XRD and XPS studies have been performed on CrAs1-xSbx in an effort obtain the phase diagram in the intermediate range (x∼0.5) in the hexagonal phase. We found that CrAs undergoes antiferromagnetic and structure transition at TN = 240K. Upon Sb substitution (x > 0.3), the Neel temperature is sharply suppressed with slope () in much similar way to the suppression caused by pressure in CrAs single crystal. The chemical compositions obtained using XPS are in good agreement with nominal values. Moreover, XPS reveals no changes in the valance states for the constituent elements of CrAs1-xSbx. Unexpectedly, we found that arsenic at the surface has higher atomic ratio than the nominal composition. This may be due to segregation of arsenic to the surface of sample.
