Magnetic phase diagrams of Cr–Ti alloys

Abstract The magnetic phase diagram of Cr–x at% Ti (0⩽x⩽10.2) is revisited. The critical temperatures were obtained from electrical resistivity and magnetic susceptibility measurements. Our results show that the antiferromagnetic phase is suppressed for x=1.3. However, previous papers predicted that the antiferromagnetic phase only disappears for x=2.0. Our results show that above x=1.3 the residual resistivity as a function of Ti concentration presents a discontinuity in these values. This change of behavior is possibly associated with a structural phase transition or a quantum phase transition.
