The interplay between magnetism and electronic band topology enriches topological phases and has promising applications. However, the role of topology in magnetic fluctuations has been elusive. Here, we report evidence for topology stabilized magnetism above the magnetic transition temperature in magnetic Weyl semimetal candidate CeAlGe.

Article Synopsis
  • Twist engineering of van der Waals magnets allows for the manipulation of unique magnetic states, but the complexity of spin interactions in large moiré superlattices complicates understanding these systems.
  • A new generic ab initio spin Hamiltonian has been developed to analyze twisted bilayer magnets, revealing strong AB sublattice symmetry breaking due to twisting that can lead to new noncentrosymmetric magnetism.
  • The study uncovers novel magnetic phases, including unique domain structures and skyrmion phases, and establishes a topological band theory of moiré magnons, providing experimental insights into these distinctive features.
