Structural Transitions and Magnetic Structure in NH4CuCl3 via 14N-NMR

open access: yes, 2005
We report results of 14N-NMR experiments on NH4CuCl3 at the magnetic field of 7 T, where the 1/4-magnetization plateau is observed at low temperatures.

Finite temperature spin dynamics in a perturbed quantum critical Ising chain with an $E_8$ symmetry [PDF]

open access: yes, 2014
A spectrum exhibiting $E_8$ symmetry is expected to arise when a small longitudinal field is introduced in the transverse-field Ising chain at its quantum critical point.

NMR Time Reversal Experiments in Highly Polarised Liquid 3He-4He Mixtures

open access: yes, 2007
Long-range magnetic interactions in highly magnetised liquids (laser-polarised 3He-4He dilute mixtures at 1 K in our experiment) introduce a significant non-linear and non-local contribution to the evolution of nuclear magnetisation that leads to ...

Gas hydrate in-situ formation and dissociation in clayey-silt sediments: An investigation by low-field NMR

open access: yes, 2020
The hydrate reservoir in the Shenhu Area of the South China Sea is a typical clayey-silt porous media with high clay mineral content and poor cementation, in which gas hydrate formation and dissociation characteristics are unclear. In this study, the CO2

Ferrimagnetism of the magnetoelectric compound Cu$_2$OSeO$_3$ probed by $^{77}$Se NMR

open access: yes, 2010
We present a thorough $^{77}$Se NMR study of a single crystal of the magnetoelectric compound Cu$_2$OSeO$_3$. The temperature dependence of the local electronic moments extracted from the NMR data is fully consistent with a magnetic phase transition from
