Interestingly, the inverse spinel NiFe2O4 compound is found to exhibit a ferrimagnetic structure. We found that energy of the normal spinel is higher than that of the inverse spinel confirming that inverse spinel is the most stable structure of NiFe2O4 compound.

Construction and Building Materials 2016, 107, 28-37. * There is a tendency of formation of inverse spinel structure in some cases (not all the cases) which contain transition metal ions. EXAMPLES FOR SPINEL AND INVERSE SPINEL STRUCTURES 1) MgAl 2 O 4 is a normal spinel since both the divalent and trivalent ions are non transition metal ions. The highly photocatalytic active magnetic NiFe 2 O 4 deposited g-C 3 N 4 hetero-structured nanocomposite was prepared by facile sol-gel followed calcination method. Among that, inverse spinel nickel ferrite (NiFe 2 O 4) attracts the researchers due to the low cost, excellent magnetic property, narrow direct bandgap ... XPS spectrum of NiFe2O4-g-C3N4 composite (a) Survey spectrum, (b) Carbon 1s, (c) Nitrogen 1s, (d) Nickel 2p, (e) Iron 2p, (f) Oxygen 1s. Background: Spinel ferrites have great scientific and technological significance because of their easy manufacturing, low cost and outstanding electrical and magnetic properties. The optical behavior of NiFe2O4 compound is characterized by calculating the real and imaginary part of the dielectric function, the absorption coefficients, the refractive index, the optical conduc-tivity and the energy loss. E.g. 2) Mn 3 O 4 is a normal spinel since the Mn 2+ ion is a high spin d 5 system with zero LFSE. If the number of spins in these two types of sites is equal, then that spinel will be antiferromagnetic. ...
