Tuning the Luttinger liquid state in copper pyrazine-based spin chain systems

The ability to manipulate quantum states of matter is a goal of condensed matter science. Recent progress in molecular magnetism has shown the potential for gaining control over the structural building blocks of materials in order to engineer quantum magnetic properties. Our muon measurements have proven particularly important in demonstrating how such structural variation influences magnetic exchange pathways. Recently we showed how the systematic tuning of the interlayer separation in a two-dimensional molecular system affects its magnetic properties. Using this insight, we now seek to systematically vary the low-dimensional superexchange pathways in a class of tuneable one-dimensional materials in attempt to gain control over the spin Luttinger liquid state. We propose here to determine the ordering temperatures and probe the 1D dynamics of two novel spin chain materials.
