43. Antiferromagnetic ordering can induce a similar resistance drop, that agrees within a factor of two with the expected change in Maxwell's resistance. In contrast to the SC signal, this antiferromagnetic drop is not really independent from the T-dependence at low temperatures, so one does not get new information.
