Spin anisotropy breaking spin degeneracy is conventionally controlled by magnetic components. Spin chiral anisotropy (SChA) (i.e., chirality-dependent spin anisotropy) can be realized through the asymmetric spin–orbit coupling (SOC) between the chiral potential and spins in chiral materials without magnetic components, in which opposite spin polarization occurs in left- and right-handed srtructures. It is important to explore the SChA of chiral materials with special magnetic components for the further development of spintronics and potential applications. Among various chiral materials, chiral mesostructured inorganic materials (CMIMs) with various intrinsic magnetisms have recently emerged as promising and intriguing materials to address these issues due to their strong SOC at multiple chiral scales ranging from the subnanometer to micrometer, as well as diverse electronic states that can be excited by multiple stimuli, such as light, heat, electric fields, and magnetic fields. We have developed accessible technology for fabricating CMIMs and characterized the spin anisotropy-related responses based on their optical, electrical, and magnetic properties.

不同本征磁性手性介观结构无机材料的自旋手性各向异性
自旋各向异性破坏自旋简并性通常由磁性元件控制。自旋手性各向异性（SChA）（即手性相关的自旋各向异性）可以通过不带磁性成分的手性材料中手性势和自旋之间的不对称自旋轨道耦合（SOC）来实现，其中相反的自旋极化发生在左旋和右手结构。探索具有特殊磁性成分的手性材料的 SChA 对于自旋电子学的进一步发展和潜在应用具有重要意义。在各种手性材料中，具有各种固有磁性的手性介观结构无机材料（CMIM）最近成为解决这些问题的有前景和有趣的材料，因为它们在从亚纳米到微米的多个手性尺度上具有很强的SOC，并且具有多种电子态可以被多种刺激激发，例如光、热、电场和磁场。我们开发了制造 CMIM 的可行技术，并根据其光学、电学和磁学特性表征了与自旋各向异性相关的响应。
