作为自旋电子学与超导物理相结合的重要纽带，三重态超导库珀对，可携带净自旋，能在铁磁材料中长程传输。因此，理论预言其产生的自旋转移力矩能够调控磁矩振荡等自旋动力学行为；而且，超导电流的零耗散性质，可最大限度地降低自旋电子学器件功耗。但是，目前对三重态超导关联的净自旋性质，及其与磁矩动力学之间的相互作用研究还不多，尤其缺乏直接的实验表征，这限制了对其物理机制的探索。本项目拟将超导/非共线铁磁多层膜与点接触型非局域纳米振荡器相结合，通过在超导转变温度附近测量纳米振荡器中磁矩振荡频率、线宽等动力学特性变化，为超导/非共线铁磁结构中产生的三重态超导关联的净自旋性质提供直接实验证据；并通过调节铁磁多层膜中磁矩非共线夹角等磁结构参数,研究三重态超导自旋流对磁矩动力学性质的调控规律。本项目将为三重态超导关联提供新的研究手段，揭示三重态超导关联与磁矩动力学相互作用的内在物理机制，促进超导自旋电子学的发展。

As an important link between spintronics and superconductivity, the triplet Cooper pairs carry a net spin component and are long-range correlated even in ferromagnetic material, making it promising to introduce spin transfer torque and influence spin dynamics. It can also minimize the power consumption of device due to the zero dissipation. However, direct experimental measurements for the net spin component of triplet superconducting correlation and its interaction with magnetization dynamics are still lacking, hindering the exploration of the underlying mechanism. In this project, we plan to combine superconductor-noncollinear magnetic multilayers with point-contact nonlocal nano-oscillator. We will provide the direct experimental evidence for the net spin component of triplet superconducting correlation by measuring the change of the magnetization oscillation properties near the superconducting critical temperature, such as frequency and linewidth. We will also study the interaction between the spin-triplet correlation and magnetization dynamics by controlling the noncollinear angle between magnetic moments in ferromagnetic multilayers. With these, we expect that this new approach to study spin-triplet correlation can be achieved and the underlying physical mechanism of the interaction can be better understood for developing superconducting spintronics.
