Abstract

Neutron diffraction experiments were performed to investigate a nature of the antiferromagnetic ordered phase below T_N = 1.6 K of the pressure-induced superconductor CeRhSi₃. We observed incommensurate magnetic reflections characterized by the wave vector Q = (± δ, 0, 0.5) (δ ∼ 0.215). The antiferromagnetic ordered state can be interpreted as a spin-density wave formation by taking account of the results on de Haas-van Alphen (dHvA) signals in CeRhSi₃ where the 4f-electrons of CeRhSi₃ are itinerant.
