Inhomogeneous ordering in weakly coupled Heisenberg $S=1/2$ chains with random bonds

M. Thede, T. Haku, T. Masuda +6

Long range magnetic ordering in the quasi-one-dimensional random-bond antiferromagnet BaCu${}_2$(Si${}_{1-x}$Ge${}_x$)${}_2$O${}_7$ is studied in $\mu$SR experiments as a function of disorde…
