Abstract
We report on substantial changes in the crystal structure as well as in the magnetic and transport properties of the La2 O 3−x F x Fe2Se2 system with x from 0.0 to 0.5 measured by neutron diffraction and magnetic bulk measurements. With increasing x, the size of the crystallographic unit cell decreases as well as the amplitude of the ordered magnetic moments, while the configuration of the magnetic order and the development of the resistivity on cooling remains unchanged.
