项目摘要
Superlattices of transition metal oxides have been formed by a laser Molecular Beam Epitaxy (MBE) technique connected with RHEED monitoring system. The superlattices of magnetics have been constructed on SrTiO_3(100), (110) and (111) surfaces. These surface selection enables us to control the three dimensional positioning of atoms and spin. In the case of LaCrO_3/LaFeO_3 superlattices on (111) surface, ferromagnetism has been realized for the first time. In the case of LaMnO_3/LaFeO_3 superlattices, on the other hand, spin frustration is expected competing with ferromagnetism of self-doped LaMnO_3 and anti-ferromagnetism of LaFeO_3 on SrTiO_3 (100) surface. Spin glass phase transition (casp shape in magnetization vs. temperature measurements) is observed in the case of LaMnO_3/LaFeO_3 superlattices. It is due to the spin frustration between ferromagnetic couping in LaMnO_3 layer and antiferromagnetic coupling in LaFeO_3 layer.
采用激光分子束外延(MBE)技术和RHEED监测系统相结合的方法制备了过渡金属氧化物超晶格。在SrTiO_3(100)、(110)和(111)表面上构筑了磁性超晶格。这些表面选择使我们能够控制原子和自旋的三维定位。在LaCrO_3/LaFeO_3(111)面超晶格中,首次实现了铁磁性。在LaMnO_3/LaFeO_3超晶格中,自旋阻挫与自掺杂LaMnO_3的铁磁性和LaFeO_3在SrTiO_3(100)表面的反铁磁性相互竞争。在LaMnO_3/LaFeO_3超晶格中观察到自旋玻璃相变(casp形状的磁化强度与温度的关系)。这是由于LaMnO_3层中的铁磁耦合和LaFeO_3层中的反铁磁耦合之间的自旋阻挫作用造成的。
