Description
Magnetization and Moessbauer studies have been carried out on GdCo3B2 and DyCo3B2. 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 DyCo3B2 at 5 K is smaller than the Dy3+ free-ion value. From 161Dy Moessbauer studies, the measured hyperfine magnetic field at the Dy site is also observed to be smaller than the free-ion value. 155Gd Moessbauer measurements in GdCo3B2 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 DyCo3B2 to be reduced from its free-ion value
