摘要：
We have measured the magnetization of single crystalline Sr3Fe2O6.5 with a lot of oxygen deficiencies. It was observed that the spin direction is parallel to the c-axis below TN. Moreover, we carried out neutron powder diffraction experiments with a Sr3Fe2O6.21 powder sample. The magnetic structure with a lot of oxygen deficiencies (δ>0.5) has a typical Ising antiferromagnet system with the magnetic unit cell \documentclass[12pt]{minimal}
