Abstract

CePdSi3 with H == [100] exhibits multiple metamagnetic transitions. Since there is no frustration in this system, it is suggested that the origin of the multiple metamagnetic transitions is the influence of the antisymmetric spin-orbit interaction. To clarify the magnetic structure under the influence of the antisymmetric spin-orbit interaction, neutron diffraction experiments have been performed using single crystal samples of CePdSi3. There are observed magnetic reflections with incommensurate magnetic propagation vector q ¼ ð0:315; 0; 0Þ in the phase I. In addition, additional magnetic reflections were also observed in the phase III. The magnetic structure was found to be an oval-cycloidal structure at the phase III in CePdSi3, and we discuss the origin of the unusual magnetic structure.
