Double　perovskite　compounds　(DPCs)　have　gained　much　more　attention　due　to　their　versatile　character　in　the　fields　of　electronics　and　spintronics.　Using　density　functional　theory　(DFT)　we　investigated　the　electronic,　magnetic　and　optical　properties　of　DPC　La2BB　＇　O-6　where　B　=　Cr,　Sc　and　V　and　B　＇　=　Co,　Ni.　The　electronic　band　gaps　suggest　these　compounds　are　half-metallic　(HF)　semiconductors　in　the　spin-up　channel　and　metallic　in　the　spin-down　channel.　Magnetic　properties　suggest　these　are　ferromagnetic　in　nature,　so　all　DPCs　are　half-metallic　ferromagnetic　(HM-FM).　Furthermore,　the　compound　La2CrCoO6　shows　outstanding　electronic　and　optical　properties,　so　it　can　be　used　in　optoelectronic/spintronic　devices.
