摘要：Structural and magnetic transitions have been investigated in our neutron scattering works on the 1111 [1], 122 [2], 11 [3] as well as the 245 [4] family of the Fe-based superconductors. Orbital ordering has been shown as the unifying mechanism of both the structural and antiferromagnetic transitions [5,6].
