Nature Communications, Published online: 01 June 2026; doi:10.1038/s41467-026-73976-3 CsCr3Sb5 is part of a family of Kagome materials noted for hosting a rich variety of emergent phases. Here, using scanning tunnelling microscopy and spectroscopy, Huang, Xu, Que, Liu and coauthors find two charge density wave orders, intertwined with a tuneable altermagnetic spin density wave order.
