Single crystal growth and study of the magnetic properties of the mixed spin-dimer system Ba${}_{3-x}$Sr${}_x$Cr${}_2$O${}_8$

Alsu Gazizulina, Diana Lucia Quintero-Castro, Andreas Schilling

The compounds Sr${}_3$Cr${}_2$O${}_8$ and Ba${}_3$Cr${}_2$O${}_8$ are insulating dimerized antiferromagnets with Cr${}^{5+}$ magnetic ions. These spin-$\frac{1}{2}$ ions form hexagon…
