| Abstract: | Magnetic ordering in the hyperfine enhanced nuclear ferromagnet PrNi5 was investigated in external magnetic fields up to 72 mT at temperatures from below the ordering temperature up to about 20 mK. An anisotropy of the magnetization and ac susceptibility was observed for two single crystalline samples having a or c crystallographic axis parallel to the external field. The results show that the nuclear magnetic moments of Pr are ordered in the basal plane of the hexagonal crystal structure of PrNi5. |
