摘要：

La0.9Sb0.1MnO3　(LSMO)　thin　films　were　deposited　on　single-crystal　LaAlO3　(001)　substrates　by　pulsed　laser　deposition　technique.　The　films　have　a　perovskite　single-phase　structure　from　X-ray　diffraction　pattern.　The　electrical　transport　and　magnetic　properties　have　been　investigated　for　La0.9Sb0.1MnO3　thin　films　with　thickness　300　nm.　The　result　indicate　that　the　film　perform　the　colossal　magnetoresistance　(CMR)　effect　with　the　maximum　magnetoresistance　(MR)　ratio　of　63%　at　temperature　of　190　K　and　field　of　2.3　T.　©　2011　IEEE.
