Magnetic-field-induced ordering in a spin-1/2 chiral chain

Rebecca Scatena, Alberto Hernandez-Melian, Benjamin M. Huddart +12

We present neutron diffraction, muon spin rotation and pulsed-field magnetometry measurements on the Heisenberg quantum chiral chain [Cu(pym)(H2O)4]SiF6.H2O, which displays a four-…

Probing magnetic order and disorder in the one-dimensional molecular spin chains CuF2(pyz) and [Ln(hfac)3(boaDTDA)]n (Ln=Sm, La) using implanted muons

T. Lancaster, B. M. Huddart, R. C. Williams +9

We present the results of muon-spin relaxation ( $μ^{+}$ SR) measurements on antiferromagnetic and ferromagnetic spin chains. In antiferromagnetic CuF $_{2}$ (pyz) we identify a transi…

Quantum-critical spin dynamics in a Tomonaga-Luttinger liquid studied with muon-spin relaxation

J. S. Möller, T. Lancaster, S. J. Blundell +7

We demonstrate that quantum-critical spin dynamics can be probed in high magnetic fields using muon-spin relaxation ( $μ^{+}$ SR). Our model system is the strong-leg spin ladder bis(…
