Using the 119Sn Mössbauer effect, the critical magnetic behavior of a single-crystal (110) Cr sample doped with at% 119Sn was investigated in the vicinity of the Néel temperature, TN. The transition from a paramagnetic to an antiferromagnetic state was found to have a double character: it is continuous and has a hysteresis of K. The latter feature has been observed for the first time. The critical exponent β of the average hf field was found to be a continuous function of the reduced temperature, t, ranging between for and for .
