摘要:

磁振子作为磁性材料最基本的激发态,近年来已成为电、热操纵和自旋输运的重要工具,磁振子场被认为是现代自旋电子学的支柱之一。另一方面,轨道电子学利用电子的轨道自由度,而不是它们的自旋,在结构复杂的材料中,它成为有效设计电流和角动量重新分配的强大平台。在这里,我们发现了一种方法来桥接世界的磁振子和电子轨道磁性,这起源于标量自旋手征的基本耦合,固有的磁振子,在固体中的轨道自由度。我们表明,这可以导致有效的产生和运输的电子轨道角动量的磁振子,从而开辟了道路相结合的磁振子和轨道电子学的功能,以他们的共同利益,在自旋电子学的应用领域。

英文摘要:

Magnons, as the most elementary excitations of magnetic materials, have recently emerged as a prominent tool in electrical and thermal manipulation and transport of spin, and magnonics as a field is considered as one of the pillars of modern spintronics. On the other hand, orbitronics, which exploits the orbital degree of freedom of electrons rather than their spin, emerges as a powerful platform in efficient design of currents and redistribution of angular momentum in structurally complex materials. Here, we uncover a way to bridge the worlds of magnonics and electronic orbital magnetism, which originates in the fundamental coupling of scalar spin chirality, inherent to magnons, to the orbital degree of freedom in solids. We show that this can result in efficient generation and transport of electronic orbital angular momentum by magnons, thus opening the road to combining the functionalities of magnonics and orbitronics to their mutual benefit in the realm of spintronics applications.
