Novel Crossover in Coupled Spin Ladders

M. Jeong, H. Mayaffre, C. Berthier +3

We report a novel crossover behavior in the long-range-ordered phase of a prototypical spin-$1/2$ Heisenberg antiferromagnetic ladder compound $({\mathrm{C}}_7{\mathrm{H}}_{10}\mathrm{N}{)}_2\mathrm{CuB}{\mathrm{r}}_4$. The…
