Study of spin mixing conductance of single oriented Pt in Pt/Ni₈₁Fe₁₉ heterostructure by spin pumping

The spin mixing conductance g↑↓ of a ferromagnetic and nonmagnetic (NM) layer characterizes the transport efficiency current through interface. Exploration relationship between structural parameters such as lattice orientation NM is critical to design effective spintronics devices. Here, two types single oriented Pt Ni81Fe19 (Py) was studied experimentally, with method pumping. obtained for (100)/Py (111)/Py bilayers 8.6 ± 0.9 nm−2 10.8 1.6 nm−2, respectively, revealing fact that crystalline metallic has no prominent impact on g↑↓, which consistent theoretical prediction.
