A thermodynamic reference for field-induced phenomena in alpha-RuCl 3: two coexisting polymorphs account for multiple magnetic phase transitions
The study mapped magnetic transitions in monoclinic alpha-RuCl3 by resolving multiple phase boundaries caused by the coexistence of monoclinic and rhombohedral crystal structures. This resolves previously unexplained oscillatory features in thermal transport, showing that these oscillations stem from the interplay between two structural phases rather than a single new magnetic phase.
