Nature, Published online: 19 March 2025; doi:10.1038/s41586-025-08725-5
Itinerant magnetism in rhombohedral multilayer graphene shows a large excess entropy from magnetic fluctuations above its critical temperature—typically only associated with local moments—which implies the decoupling of charge and isospin degrees of freedom, and results in the isospin Pomeranchuk effect.Drivers of avian genomic change revealed by evolutionary rate decomposition
