    The antiferromagnetic ordering in Pr due to the coupling of the 4f electronic system to the nuclei and to magnetic Nd impurities has been studied by neutron diffraction. A pure monocrystal of Pr develops true long-range order at about 50-60 mK. The ordering in both this crystal and a PrNd alloy is, however, presaged by unusually intense and longrange magnetic fluctuations, which are ascribed to the special form of the exchange interactions.
