Hyperfine interactions ofAl27in paramagnetic DyAl2and GdAl2

Abstract
Nuclear magnetic resonance was used to measure the parameters of the hyperfine interactions of Al27 in DyAl2 and GdAl2. In both compounds the Al27 paramagnetic shift exhibits a Curie-Weiss law behavior. The hyperfine field and the quadrupole splitting agree well with the corresponding parameters in the ferromagnetic phase.
