本文选择Nb掺杂的SrNbxTi1 xO3 (SNTO)作为n型衬底材料 ,利用激光分子束外延 (LMBE)生长La1 xCaxMnO3 (LCMO)巨磁阻薄膜作为P型材料 ,人工合成了巨磁阻锰氧化物异质结。这种异质结不仅具有良好的p n结特性 ,而且具备其他特殊的物理性质。一般认为LCMO巨磁阻薄膜材料中具有负的C
In this paper, Nb-doped SrNbxTi1xO3 (SNTO) was chosen as the n-type substrate material, and La1xCaxMnO3 (LCMO) giant magnetoresistive film was grown by laser molecular beam epitaxy (LMBE) Heterojunction. This heterojunction not only has good p n junction characteristics, but also has other special physical properties. It is generally believed that the LCMO giant magnetoresistive thin film material has a negative C
