We investigate the spin to charge conversion phenomena in Y3Fe5O12/Pt/Co1-xTbx/Pt multilayers by both the spin pumping and spin Seebeck effects.We find that the spin transport efficiency is irrelevant to magnetization states of the perpendicular magnetized Co;Tb;films,which can be attributed to the symmetry requirement of the inverse transverse spin Hall effect.Furthermore,the spin transmission efficiency is significantly affected by the film concentration,revealing the dominant role of extrinsic impurity scattering caused by Tb impurity.The present results provide further guidance for enhancing the spin transport efficiency and developing spintronic devices. 相似文献

萃取分离ICP-AES法测定高纯金中的杂质元素 总被引:11,自引:0,他引:11
通过用有机溶剂甲基异丁基酮(MIBK)在10%的盐酸溶液中萃取高纯金(99.99%)中的基体元素,使得大量的金得以分离,消除了基体的存在对杂质元素测定的干扰,使微量的杂质元素的测定成为可能,进而用等离子体发射光谱仪测定了高纯金中Cd,Cr,Cu,Fe,Mn,Ni,Pb,Pt等元素的含量。 相似文献
