论文摘要
我们报告了交错分子自旋链[Pym-Cu（no $ _3 $）$ _ 2 $（H $ _2 $ _2 $ _ 2 $]（PYM = pyrimidine），Muon-Spin光谱（$μ^+$ sr）的结果（pym-cu（no $ _3 $），先前使用Sine-Gordon Field Field理论）。 Zero-field $μ^+$SR reveals a long range magnetically-ordered ground state below a transition temperature $T_\mathrm{N}=0.22(1)$ K. Using longitudinal-field (LF) $μ^+$SR we investigate the dynamic response in applied magnetic fields $0< B < 500$ mT and find evidence for ballistic spin transport.我们的LF $μ^+$ $ SR测量值[Cu（pym）（h $ _2 $ o）$ _ 4 $] SIF $ _6 \ cdot $ h $ _2 $ o而不是表现出一维旋转扩散，并且在这两个系统中的独特旋转运输可能反映了他们的磁兴奋性差异。
We report the results of muon-spin spectroscopy ($μ^+$SR) measurements on the staggered molecular spin chain [pym-Cu(NO$_3$)$_2$(H$_2$O)$_2$] (pym = pyrimidine), a material previously described using sine-Gordon field theory. Zero-field $μ^+$SR reveals a long range magnetically-ordered ground state below a transition temperature $T_\mathrm{N}=0.22(1)$ K. Using longitudinal-field (LF) $μ^+$SR we investigate the dynamic response in applied magnetic fields $0< B < 500$ mT and find evidence for ballistic spin transport. Our LF $μ^+$SR measurements on the chiral spin chain [Cu(pym)(H$_2$O)$_4$]SiF$_6 \cdot $H$_2$O instead demonstrate one-dimensional spin diffusion and the distinct spin transport in these two systems likely reflects differences in their magnetic excitations.
