Anisotropy of Magnetic Interactions in the Spin-Ladder Compound (C${}_5$H${}_{12}$N)${}_2$CuBr${}_4$

E. Čižmár, M. Ozerov, J. Wosnitza +8

Magnetic excitations in the spin-ladder material (C${}_5$H${}_{12}$N)${}_2$CuBr${}_4$ [BPCB] are probed by high-resolution multi-frequency electron spin resonance (ESR) spectroscopy. Our e…
