Na order and diffusion in NaxCoO2: Part II
Recently there have been reports that high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at low... -
One- and multi-magnon excitations in a strong-leg quantum spin ladder
We propose to measure the one- and multi-magnon excitations in the first realization of a S=1/2 quantum spin ladder in the strong-leg regime. Our material, DIMPY, has very well... -
Doping-induced energy gap in a quantum spin chain
SrCuO2 is a prototypical S = 1/2 antiferromagnetic (AF) Heisenberg 1D spin chain system. High-resolution neutron scattering studies has already successfully revealed the gapless... -
Na order and diffusion in NaxCoO2: Part II
Recently there have been reports that high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at low... -
Probing the random singlet state in antiferromagnetic Heisenberg spin chain c...
Low-dimensional quantum spin systems with introduced disorder are a fascinating playground for investigations of the interplay between quantum effects, strong correlations and... -
Ion dynamics in Potassium Ordered & Disordered KxCoO2
We have recently presented a novel method to study ion-dynamics in solids using muSR via the hopping rate (nu). We have previously and successfully applied this method to study... -
What is the cause for the gapped mode in the `BEC' phase of DTN?
Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an...
