Abstract	本发明提供了一种异质结材料及其制备方法和用途。所述异质结材料包括SrIrO3层以及位于所述SrIrO3层上的锰氧化物层。所述制备方法包括：(1)沉积SrIrO3层；(2)在SrIrO3层上沉积锰氧化物层，得到所述异质结材料。本发明提供的异质结材料通过异质结界面极性不连续和SrIrO3中强自旋‑轨道耦合能的共同作用下驱动了异质结界面的非对称电荷转移。通过调节异质结界面的极性不连续性以及连同SrIrO3中强的自旋耦合能，可以有效地调控界面电荷转移的程度，从而实现调节异质结材料界面的磁耦合性能。
Other Abstract	The invention provides a heterojunction material as well as a preparation method thereof and application thereof. The heterojunction material comprises a SrIrO3 layer and a manganese oxide layer located on the SrIrO3 layer. The preparation method comprises the following steps: (1) depositing a SrIrO3 layer; and (2) depositing a manganese oxide layer on the SrIrO3 layer to obtain a heterojunction material. According to the heterojunction material provided by the invention, the asymmetric charge transfer of a heterojunction interface is driven under the combined action of polarity discontinuityof the heterojunction interface and strong spin-orbit coupling energy in SrIrO3. By adjusting the polarity discontinuity of the heterojunction interface and the strong spin coupling energy in SrIrO3,the degree of interface charge transfer can be effectively adjusted and controlled such that the magnetic coupling performance of the heterojunction material interface is adjusted.
