摘要：

The　polycrystalline　La0.62Sb0.38MnO3　sample　has　been　prepared　by　the　solid-state　reaction　method.　Structural,　magnetic　and　electrical　transport　properties　have　been　researched.　X-ray　diffraction　analysis　confirms　the　hexagonal　crystal　symmetry.　Magnetization　measurements　indicate　La062Sb0.38MnO3　experienced　from　paramagnetic　to　ferromagnetic　state　transition　with　decreasing　temperature　at　about　225　K.　Resistivity　dependences　on　temperature　exhibit　metal-insulator　transition　(MIT),　and　the　maximum　magnetoresistance　(MR)　ratio　is　about　33%　at　temperature　of　189　K　and　magnetic　field　of　2　T.　©　(2013)　Trans　Tech　Publications,　Switzerland.
