Spin diffusion in the low-dimensional molecular quantum Heisenberg antiferromagnet Cu(pyz)(NO${}_3$)${}_2$ detected with implanted muons

F. Xiao, J. S. Möller, T. Lancaster +6

We present the results of muon-spin relaxation measurements of spin excitations in the one-dimensional quantum Heisenberg antiferromagnet Cu(pyz)(NO${}_3$)${}_2$. Using density-fun…
