Low dimensional systems are among the prime places to look for interesting emergent magnetic behavior in quantum systems. We have recently been studying a metal-organic coordination compound – (C5H9NH3)2CuBr4, or Cu-CPA for short, where magnetic properties are dictated by the one dimensional ladders of S=1/2 copper ions. Surprisingly, we have found that in fact there are two distinct ladders and not just one as was previously assumed. To learn more about the structure (and a cool isotope effect), have a look at the preprint: https://arxiv.org/abs/2404.08274
