Magnetic ordering in the ultra-pure site-diluted spin chain materials SrCu${}_{1-x}$Ni${}_x$O${}_2$

G. Simutis, M. Thede, R. Saint-Martin +8

Muon spin rotation technique is used to study magnetic ordering in ultra-pure samples of SrCu${}_{1-x}$Ni${}_x$O${}_2$, an archetypical $S=1/2$ antiferromagnetic Heisenberg chain system…
