Tuning the orbital-lattice fluctuations in the mixed spin-dimer system Ba${}_{3-x}$Sr${}_x$Cr${}_2$O${}_8$

Alsu Gazizulina, Diana Lucia Quintero-Castro, Dirk Wulferding +4

In $A_3$Cr${}_2$O${}_8$, where $A$ = Sr or Ba, the Cr${}^{5+}$ ions surrounded by oxygen ions in a tetrahedral coordination are Jahn-Teller active. The Jahn-Teller distortion leads…
