The magnetic properties including the magnetic structure were determined by magnetometric and neutron diffraction measurements of the polycrystalline samples of R_{2} PdSi_{3} (R = Ce, Nd, Tb-Er). In Ce_{2}PdSi_{3} the Ce moments order below 2.5 K. The Nd magnetic moments in Nd_{2}PdSi_{3} exhibit ferromagnetic ordering below 17 K. In Tb_{2}PdSi_{3}, a complex situation is observed: in the temperature range from 1.5 K to (T_{N}=25 K), there is a coexistence of a ferromagnetic spiral (about 75% of the magnetic moment) and a spin-glass (about 25%). For the Dy, Ho, and Er compounds, below T_{N} (7.5, 8, and 7 K respectively), sinusoidally modulated structures are observed. The valence band and the core level photoemissions of 4d of rare-earth metal, 3d Pd, 2s and 2p Si were investigated by X-ray photoemission spectroscopy measurements.
