摘要：
Rhombohedral Cr2Se3 is an antiferromagnetic compound with antiferromagnetic AF(L) phase below 38 K (= T(t)) and the antiferromagnetic AF(H) one between 38 K and 45 K (= TN). Neutron diffraction studies for rhombohedral Cr2Se3 are carried out at temperatures from 6 K to 77 K. The results show that the magnetic structures of AF(L) and AF(H) phase are a non-collinear and collinear antiferromagnetic structures, respectively, with the monoclinic magnetic unit cell. It was found that Cr moments at the a-sites are frustrated in the AF(H) phase.
