论文摘要
我们研究了由于非常规配对对铁磁性/超导体连接的逆接近效应而导致的Andreev结合状态的影响。利用准经典艾伦伯格理论，我们获得了穿透超导体的磁化。我们表明，在广泛的参数范围内，诱导的磁化的方向由两个因素确定：Andreev绑定状态是否存在于接口接口处和自旋混合角的符号。特别是，当Andreev绑定状态出现在界面处时，诱导磁化的方向与没有Andreev结合状态的磁化态相反。我们还阐明了倒置诱导磁化的条件。应用这种新颖的效果有助于区分超导体的配对对称性。
We investigate the effects of Andreev bound states due to the unconventional pairing on the inverse proximity effect of ferromagnet/superconductor junctions. Utilizing quasiclassical Eilenberger theory, we obtain the magnetization penetrating into the superconductor. We show that in a wide parameter range the direction of the induced magnetization is determined by two factors: whether Andreev bound states are present at the junction interface and the sign of the spin-mixing angle. In particular, when Andreev bound states appear at the interface, the direction of the induced magnetization is opposite to that without Andreev bound states. We also clarify the conditions under which the inverted induced magnetization appears. Applying this novel effect helps distinguishing the pairing symmetry of a superconductor.
