Prediction of Magnetic Topological Materials Combining Spin and Magnetic Space Groups
The research introduces a new method combining Spin Space Groups (SSGs) and Magnetic Space Groups (MSGs) to find electronic topology in collinear magnetic materials. By analyzing 484 synthesized magnets, the scheme reveals nontrivial band topology that conventional MSG methods miss. This approach uses symmetry indicators to systematically classify materials, showing how spin-orbit coupling affects topological features.
