A method for measuring hyperfine interactions in magnetic materials by gamma -- gamma anfular correlation techniques is discussed. The change in the anisotropy of the 1415-122 Kev gamma -- gamma angular correlation following the K capture of Eu/sup 152/ in neutron irradiated polycrystalline samples of Europium iron garnet enriched in Eu/sup 151/ has been measured as a function of temperature without applied magnetic field, and the rotation of the angular correlation pattern was observed when a magnetic field was applied perpendicular to the plane containing the gamma counters. From these experiments, the effective magnetic field acting at the europium nuclei immediately after the radioactive decay can be obtained. (auth)
