外文摘要：Anisotropy is a significant and prevalent characteristic of materials,conferring orientation-dependent properties,meaning that the creation of original symmetry enables key functionality that is not found in nature.Even with the advancements in atomic machining,synthesis of separated symmetry in different directions within a single structure remains an extraordinary challenge.Here,we successfully fabricate NiS ultrafine nanorods with separated symmetry along two directions.The atomic structure of the nanorod exhibits rotational symmetry in the radial direction,while its axial direction is characterized by divergent translational symmetry,surpassing the conventional crystalline structures known to date.It does not fit the traditional description of the space group and the point group in three dimensions,so we define it as a new structure in which translational symmetry and rotational symmetry are separated.Further corroborating the atomic symmetric separation in the electronic structure,we observed the combination of stripe and vortex magnetic domains in a single nanorod with different directions,in accordance with the atomic structure.The manipulation of nanostructure at the atomic level introduces a novel approach to regulate new properties finely,leading to the proposal of new nanotechnology mechanisms.
