We investigate structural, magnetic, and electronic properties of SrFeAsF asa new parent for superconductors using state-of-the-art density-functionaltheory method. Calculated results show that striped antiferromagnetic order isthe magnetic ground state in the Fe layer and interlayer magnetic interactionis tiny. Calculated As and Sr positions are in agreement with experiment. Thereare only two uniaxially-dispersed bands near the Fermi level. The valent chargeis mainly in the Fe and F layers, and the magnetic moment is confined to the Featoms. Inter-Fe-spin couplings is due to superexchange through As atoms. Theseare useful to understanding the SrFeAsF and should have helpful implications todoped samples.
