论文摘要
从理论上讲，我们研究了弱磁化对介质接近结构状态局部密度的影响，其中两个超导末端连接到具有相位差的扩散铁磁铁线的侧面。当没有相位差异时，在旋转singlet $ s $ - 波和旋转三键$ p $ - 波盒中的磁化情况下，状态的局部密度会显着改变。当相位差为$π$时，由于库珀对的破坏性干扰，与磁化相比，磁化强度的局部密度被磁化的修饰较少。
We theoretically investigate the effects of the weak magnetization on the local density of states of mesoscopic proximity structures, where two superconducting terminals are attached to a side surface of the diffusive ferromagnet wire with a phase difference. When there is no phase difference, the local density of states is significantly modified by the magnetization in both spin-singlet $s$-wave and spin-triplet $p$-wave cases. When the phase difference is $π$, the local density of stets is less modified by the magnetization compared with the in-phase case because of the destructive interference of Cooper pairs.
