The review is devoted to the fundamental aspects and characteristic features of the magnetoelectric effects, reported in the literature on Josephson junctions (JJs). The main focus of the review is on the manifestations of the direct and inverse magnetoelectric effects in various types of Josephson systems. They provide a coupling of the magnetization in superconductor/ferromagnet/superconductor JJs to the Josephson current. The direct magnetoelectric effect is a driving force of spin torques acting on the ferromagnet inside the JJ. Therefore it is of key importance for the electrical control of the magnetization. The inverse magnetoelectric effect accounts for the back action of the magnetization dynamics on the Josephson subsystem, in particular, making the JJ to be in the resistive state in the presence of the magnetization dynamics of any origin. The perspectives of the coupling of the magnetization in JJs with ferromagnetic interlayers to the Josephson current via the magnetoelectric effects are discussed.
这篇综述致力于约瑟夫森结(JJs)文献中报道的磁电效应的基本方面和特征。综述的主要重点是各种类型约瑟夫森系统中直接和逆磁电效应的表现。它们实现了超导体/铁磁体/超导体结中磁化与约瑟夫森电流的耦合。直接磁电效应是作用于结内铁磁体的自旋扭矩的驱动力。因此,它对于磁化的电控制至关重要。逆磁电效应解释了磁化动力学对约瑟夫森子系统的反向作用,特别是在存在任何起源的磁化动力学时使结处于电阻状态。讨论了通过磁电效应将具有铁磁中间层的结中的磁化与约瑟夫森电流耦合的前景。
