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... -
Study of possible quantum chains in Nd2Zr2O7 in high [110] fields
Nd2Zr2O7 is a new candidate prominent to quantum spin ice proposed theoretically. It has a well-isolated dipolar-octupolar doublet with Ising anisotropy as the crystal field... -
One Dimensional Metal Chains on a Frustrated Triangular Lattice.
Nature abhors disorder and degeneracy at low temperature. Designing materials that confront this requirement can therefore lead to new states in which the degeneracy is lifted.... -
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... -
Investigation of a new three-dimensional frustrated quantum magnet
Interesting behaviour in Heisenberg spin systems originates from networks of triangles or tetrahedra, where spins interact via antiferromagnetic interactions. In 3D there are... -
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.... -
Is the anisotropic resistivity in Sr3Ru2O7 due to imbalanced antiferromagneti...
Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....
