摘要：
Magnetic structure of single-crystalline Ce(Ru1-xPdx)(2)Si-2, x = 0.025 has been measured by neutron diffraction. The magnetic moment is oriented and modulated along the c-axis with incommensurate wave vector tau = (0,0,0.368). At 1.4 K the moment was estimated to be about 0.15 mu(B). Temperature dependence of the specific heat on polycrystalline Ce(Ru1-xPdx)(2)Si-2, x = 0.05 has also been measured in various magnetic fields, suggesting partial gapping of the Fermi surface due to a Fermi-surface nesting.
