Abstract
From hyperfine-specific-heat measurements at very low temperatures we conclude that the ground state in double hcp Pr single crystals must be a magnetically ordered state. Within experimental error the hyperfine specific heat in a single crystal is in agreement with data on polycrystalline material. This is surprising since recent neutron-scattering data in Pr single crystals do not indicate any magnetic order down to 1.7°K, while neutron-scattering data on polycrystalline samples indicated antiferromagnetic order with a Néel temperature of 25°K.Keywords
