Understanding the evolution of the magnetic ground state in Ba${}_4$NaRu${}_3$O${}_{12}$

Shruti Chakravarty, Pascal Manuel, Antonio Cervellino +1

We report a comprehensive investigation of the quadruple perovskite Ba${}_4$NaRu${}_3$O${}_{12}$, in which we discover a robust spin-lattice coupled ground state characterized by a long-…
