摘要:

研制了一种界面可控的铂(Pt)/钇铁石榴石(YIG)双层膜系统,研究了Pt/YIG界面的自旋混合电导。实验证明,在界面处的晶体完整性有助于大的自旋混合电导。在良好控制的Pt/YIG界面处得到自旋混合电导为$1.3\times10^{18} \rm{m^{-2}}$,这接近于理论预测。

英文摘要:

A platinum (Pt)/yttrium iron garnet (YIG) bilayer system with a well-controlled interface has been developed; spin mixing conductance at the Pt/YIG interface has been studied. Crystal perfection at the interface is experimentally demonstrated to contribute to large spin mixing conductance. The spin mixing conductance is obtained to be $1.3\times10^{18} \rm{m^{-2}}$ at the well-controlled Pt/YIG interface, which is close to a theoretical prediction.
