We have performed inelastic neutron scattering experiments to examine the magnetic ordering in U3Pd20Si6, which exhibits antiferromagnetic ordering at TN = 19 K and ferromagnetic ordering at TC = 2 K. We observed that both antiferromagnetic spin wave excitations due to the magnetic moments at the 8c site and ferromagnetic ones due to the magnetic moments at the 4a site coexisted below TC = 2 K. Our results indicate direct experimental evidence that U3Pd20Si6 is a rare localized 5f electron system in uranium intermetalic compounds, with coexistence of both antiferromagnetic and ferromagnetic ordering. The anomolous line width around the zone center is also discussed.
