Anisotropy-induced soliton excitation in magnetized strong-rung spin ladders

Yu. V. Krasnikova, S. C. Furuya, V. N. Glazkov +3

We report low temperature electron spin resonance experimental and theoretical studies of an archetype $S=1/2$ strong-rung spin ladder material (C${}_5$H${}_{12}$N)${}_2$CuBr${}_4$.…
