研制了一种界面控制良好的铂(Pt)/钇铁石榴石（YIG）双层体系；研究了Pt/YIG界面的自旋混合电导。实验证明，清晰的界面和良好的晶体完美性是最终自旋混合电导的重要因素之一。在控制良好的Pt/YIG界面处，得到的自旋混合电导率为1.3 x 10(18) m(-2)，接近理论预测。(C) 2013 AIP出版有限责任公司
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. A clear interface with good crystal perfection is experimentally demonstrated to be one of the important factors for an ultimate spin mixing conductance. The spin mixing conductance is obtained to be 1.3 x 10(18) m(-2) at the well-controlled Pt/YIG interface, which is close to a theoretical prediction. (C) 2013 AIP Publishing LLC.
