利用中子衍射实验研究了压力感应超导体CeIrSi3在T N= 5.0K以下的反铁磁有序相的性质。我们成功地观测到了波矢为τ=（± 0.265，0，0.43）的无公度磁峰。与CeRhSi 3的磁结构相反，所观察到的磁结构在沿着a和c方向都是无公度的. CeIrSi3中的反铁磁有序态可以解释为自旋密度波的形成。
Neutron diffraction experiments were performed to investigate a nature of the antiferromagnetic ordered phase below T N= 5.0 K of the pressure-induced superconductor CeIrSi 3. We succeeded in observing incommensurate magnetic peaks characterized by the wave vector τ=(±0.265, 0, 0.43). In contrast to the magnetic structure of CeRhSi 3, the observed magnetic structure is incommensurate both along the a and c directions. The antiferromagnetic ordered state in CeIrSi 3 could be interpreted as a spin-density wave formation.
