Cerium　ferrite　(CeFeO3)　thin　films　doped　with　vanadium　(V:CeFeO3)　were　grown　on　SiO2　quartz　glass　and　＜100＞-oriented　SrTiO3　(STO)　crystal　substrates　by　the　radio-frequency　magnetron　sputtering　method　in　this　study.　The　effects　of　crystallization,　substrate,　and　V-doping　on　the　quality,　the　magnetic　property　and　the　magneto-optical　property　of　as-prepared　films　are　investigated.　V:CeFeO3　film　grown　on　STO　substrate　has　better　crystallinity　and　has　better　lattice　integrity　due　to　the　higher　lattice　matching　between　substrate　and　film.　The　magnetic　hysteresis　loop　and　the　magnetic　circular　dichroism　spectra　show　that　the　magnetization　strength　and　the　magneto-optical　properties　of　V:CeFeO3　films　have　the　significant　anisotropy.　Moreover,　V-doping　and　the　stress　lead　to　the　change　in　easy　magnetization　direction　of　film.　It　shows　that　the　perovskite　B-site　doping　with　transition-metal　ion　has　significant　influence　on　the　magnetic　and　the　magneto-optical　properties　of　CeFeO3　thin　films.
