| Summary: | 碩士 === 國立中山大學 === 物理學系研究所 === 92 === (La0.67Sr0.33MnO3)˙(SrO), LSMO214(n=1) in short, is 2-D magnetic insulator with a structure very similar to the 3D La0.67Sr0.33MnO3 and La0.67Ca0.33MnO3, 113(n=1) in short, which consists of superstructure of a subsequent magnetic layers and insulating layers. Forming a single 214 phase bulk is not easy, a mix phase of 2<n<∞ compounds is usually seen.
Due to the lattice mismatch between Substrate and bulk,strain has been an important factors of magnetic resistance and electrical properties.
Studying single layer and multi-layer films,we find because the small of growth condition scope and lattice mismatch,the LSMO214 films consists mix phases of higher n.
