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 
.
