The unprecedented phenomenon that a charge density wave (CDW) emerges inside the antiferromagnetic (AFM) phase indicates an unusual CDW mechanism associated with magnetism in FeGe. Here, we demonstrate that both the CDW and magnetism of FeGe can be effectively tuned through postgrowth annealing treatments. Instead of the short-range CDW reported earlier, a long-range CDW order is realized below 110 K in single crystals annealed at 320 °C for over 48 h.

- Topology is a crucial mathematical field used to describe topological states and phase transitions, often using topological invariants defined on surfaces like the torus and sphere.
- Researchers have investigated non-orientable surfaces, revealing that spin-induced ferroelectric polarizations in cubic perovskite oxides (AMnCrO) correspond to the topological Roman surface, which combines a Möbius strip with a disc.
- This study highlights how induced polarization can follow different paths based on external magnetic fields, leading to new insights into the relationship between topology in mathematics and its physical applications.
