Abstract：

This　paper　focuses　on　strong　magneto-optical　thin　films　that　closely　match　a　Si　substrate.　The　orthorhombic　perovskite　crystal　structure　of　CeFeO3was　optimized　to　a　cubic　perovskite　structure　by　introducing　strontium　and　vanadium　ions　into　lattice.　The　cubic　Ce1−xSrxFe1−xVxO3(x=　0.3,　0.5,　0.7)　thin　films　with　high　quality　and　high　growth　orientation　were　prepared　on　a　Si　substrate　by　using　the　RF　magnetron　sputtering　method.　Moreover,　the　birefringence　effect,　which　may　weaken　the　magneto-optical　effect,　should　not　occur　in　the　cubic　thin　film.　The　calculation　results　based　on　density　functional　theory　show　that　the　increased　electronic　transition　probability　is　attributed　to　the　strong　spin-coupling　between　the　hybrid　Ce3+4f　and　Fe3+/V4+3d　states.　The　magnetic　circular　dichroism　ellipticity　|ΨF|　of　the　Ce0.7Sr0.3Fe0.7V0.3O3thin　film　is　up　to　4300　deg.　cm−1,　which　indicates　a　strong　magneto-optical　effect.　Therefore,　the　cubic　Ce1−xSrxFe1−xVxO3/Si　film　with　high　Ce3+concentration　is　expected　to　be　a　new　candidate　for　integrated　magneto-optical　devices.　©　The　Royal　Society　of　Chemistry　2020.
