Abstract
The spinel oxides SnV(2)O(4)and SnCr(2)O(4)are analysed to reveal the mechanical, electronic and magnetic properties using Wien2k software. The negative formation energy and positive elastic constants shows the studied materials are thermodynamically and mechanically favorable. In ferromagnetic (FM) state more energy release than antiferromagnetic (AFM) state. The above room temperature magnetism is elaborated by spin polarisation, exchange mechanism, direct Delta(x)(d) and indirect Delta(x)(pd) exchange energy and crystal field energy Delta(x)(CF). The shifting of magnetic moment form V/Cr sites to Sn/V sites illustrate the ferromagnetism is caused bypdhybridisation that affects the net orientation of electrons spin and hence, it increases the importance of the materials for spin-dependent electronic applications.
