Cr and its dilute alloys exhibit intriguing magnetic properties resulting from their itinerant antiferromagnetic state due to spin density wave (SDW). This study successfully established the magnetic phase diagram for spin-flip transition of CrNb alloys, in the compositional range represented by Cr(x)Nb(1-x )with 0 <= xat% <= 3.5. The findings revealed a parabolic dependence between Nb concentration and the transition temperature T-SF. It is noteworthy that the critical temperature ratio T (SF)/T-N falls within the range predicted by the Varelogiannis model, conclusively supporting the model's applicability of this model to itinerant antiferromagnetic SDW systems in general and Cr alloys in particular.
