Frustration relief and reorientation transition in the kagome-like dolerophanite Cu${}_2$OSO${}_4$

Amelia Panther, Alexander A. Tsirlin, Ioannis Rousochatzakis

We present a theoretical study of dolerophanite Cu${}_2$OSO${}_4$, a layered kagome-like spin-$\frac{1}{2}$ magnetic insulator that can be described either as a system of chains couple…
