Abstract:
It is predicted that the oxygen behaviour in A-site may be different from that of B-site. The magnetic behaviour of oxygen in alkaline ferrites having the composition AFe2O4 (A = Mg, Ca and Sr) has been discussed using electronic structure calculations. The calculations have shown that the physical properties of the studied compounds are exclusively sensitive to the magnetic moment carried by the 2p-electrons of the oxygen anions. The compounds, with A = Ca, Sr and Ba, have a closely related electronic structures different from MgFe2O4.
