Results of measurements of magnetic susceptibilities and anisotropies of Dy2Ge207 (DyPG) between 300 and 23 K are reported here. Crystal-field (CF) analysis under D51, site symmetry was performed to explain the magnetic results. With use of the parametrized CF interaction and intermediate-coupling formalism, the positions of difterent spectral lines were calculated and matched with earlier observations. At low temperature DyPG behaves almost like an Ising S=~s ystem with g~~= 1.293+0.01 and g& = 10.301+0.02. The calculated values of saturated magnetization along the D5& symmetry axis and its perpendicular were found to be 82.58 and 659.41 emu/cm', respectively. The nuclear hyperfine field and quadrupole interactions (associated with strong asymmetric CF) give rise to appreciable nuclear hyperfine splitting for DyPG. More hyperflne lines than usual were predicted in the Mossbauer spectra.
