Magnetization and Moessbauer studies have been carried out on GdCo/sub 3/B/sub 2/ and DyCo/sub 3/B/sub 2/. These compounds are magnetically ordered with Curie temperatures of 56 and 21 K, respectively. The Co atoms are either nonmagnetic or carry a small moment in these compounds. The saturation moment of DyCo/sub 3/B/sub 2/ at 5 K is smaller than the Dy/sup 3 +/ free-ion value. From /sup 161/Dy Moessbauer studies, the measured hyperfine magnetic field at the Dy site is also observed to be smaller than the free-ion value. /sup 155/Gd Moessbauer measurements in GdCo/sub 3/B/sub 2/ reveal the presence of large crystalline electric fields at the rare-earth site. This causes the moment and the hyperfine field at the Dy site in DyCo/sub 3/B/sub 2/ to be reduced from its free-ion value.
