The full spin-wave dispersion of CaFe2O4 in the A and B phases:
CaFe2O4 shows an interplay between magnetic structures termed the A and B phases. In this proposal, we request time to measure the spin wave dispersion using MERLIN. Previous... -
Unravelling spin fluctuation components in a stripe-ordered cuprate
In previous experiments at ILL we observed a gap in the magnetic excitation spectrum of the stripe-ordered superconductor (La,Nd)2-xSrxCuO4, x=0.12. We observed a spin gap of... -
Phonons and disorder in Yb2Ti2O7
The pyrochlores provide an excellent model system for studying the interaction of framework vibrational modes, defects and magnetism. We propose to investigate these couplings... -
Magnon-phonon coupling in magnetoelectric HoMnO3
The manipulation of magnetic properties electronically is of great importance in modern computing. Current technology uses electric currents which draws a relatively large... -
Determination of the Spinon Confining Potential in a 1D, Spin-1/2 XXZ Antifer...
SrCo2V2O8 is a quasi-1D, S-1/2 antiferromagnet with XXZ anisotropy. Weak interchains coupling result in long-range magnetic order at a finite temperature TN. A spinon continuum... -
Phonon Anomalies in Charge-Density-Wave Ordered La2-xSrxCuO4
It has been known for some time that the CuO bond-stretching phonon in the high-temperature superconductor La2-xSrxCuO4 (LSCO) exhibits anomalies is its dispersion and damping....
