Title: 铁性旋转系统中的旋转诱导轨道电流

Abstract: Generation of orbital angular momentum has become important to effectuate new ways to address switchable magnetic devices. Here, we demonstrate the electrical generation of unconventional orbital currents in ferro-rotational systems through an intrinsic, nonrelativistic mechanism associated with an electric hexadecapole moment. These rotation-induced orbital currents are examined using tight-binding models, and we also provide first-principles calculations for the ferro-rotational material TiAu$_4$. Our findings unveil a novel pathway for generating orbital currents beyond the conventional orbital Hall effect, broadening the landscape of orbitronics research to include novel ferroic materials and higher-order electric multipoles.

Abstract: 轨道角动量的产生已成为实现新型开关磁性器件的重要手段。 在这里，我们通过与电十六极矩相关的固有非相对论机制，在铁性旋转系统中展示了非常规轨道电流的电生成。 这些由旋转引起的轨道电流使用紧束缚模型进行了研究，并且我们还为铁性旋转材料TiAu$_4$提供了第一性原理计算。 我们的发现揭示了一种超越传统轨道霍尔效应的新途径来生成轨道电流，从而扩大了轨道电子学研究的范围，包括新型铁性材料和高阶电多极矩。
