Special Issue Information

Dear Colleagues,

Spin chirality, with its profound impact on magnetic properties and behaviors, has emerged as a prominent area of investigation within the realm of molecular magnetism and symmetry relation. The interplay between the spatial arrangement of spins and their chiral characteristics gives rise to intriguing phenomena and holds immense potential for both fundamental studies and technological applications. 

This Special Issue aims to provide a comprehensive platform for disseminating the latest advancements in spin chirality and its connection with symmetry relation. We welcome original research articles and reviews that address various aspects of this field, including but not limited to the following:

  1. Theoretical and experimental investigations of chiral-induced spin selectivity and its connection with symmetry relation;
  2. Chirality and spin dynamics in molecular magnets;
  3. Chiral magnetic textures and their manipulation;
  4. Chirality in topological materials and its impact on spin transport;
  5. How symmetry relation affects the magnetism in various materials. 

We believe that this Special Issue will not only provide a valuable platform for researchers to share their latest findings but also contribute to the advancement of spin chirality research and its impact on molecular magnetism.  We look forward to your participation and the opportunity to showcase the remarkable progress being made in this field.

Previous studies have demonstrated that the surface curvature of cylindrical magnetic nonawires can induce fascinating dynamic magnetization properties. It was recently proposed that ferromagnetic nanotubes can be utilized as skyrmion guides, enabling the avoidance of the annihilation of skyrmions in the lateral boundaries as in flat thin-film strips. In this work, we demonstrate via micromagnetic simulation that multiple skyrmions can be stabilized in a cross-section of a ferromagnetic nanotube with interfacial Dzyaloshinskii–Moriya interaction (iDMI). When uniformly arranged, these skyrmions together can perform as a crystal lattice for spin waves (SWs) propagating in the nanotube. Our simulations show that the skyrmion lattice can contribute a chiral effect to the SW passing through, namely a circular polarization of the SW. The handedness of the polarization is found to be determined by the polarity of the skyrmions. A physical explanation of the observed effect is provided based on the exchange of angular momentum between SWs and skyrmions during the scattering process. Our results display more possibilities to exploit magnetic nanotubes as SW and skyrmion guide in the development of novel spintronic devices. Full article
