Investigation of the fine effect of the Dzyaloshinski-Moryia interaction on t...
The highly frustrated nature of the pyrochlore lattice leads to a rich diversity of fascinating properties when the lattice sites are decorated with classical spins. Arguably... -
Magnon decay below the critical field in the S=1/2 Heisenberg antiferromagnet...
In this continuation proposal, we propose to study the spin excitations of the spin 1/2 square lattice Heisenberg antiferromagnet CAPCC in fields just below its saturation... -
Correlated triplon decay and Correlated multi-triplon propagation in the Shas...
We propose to continue our investigation on LET of the Shastry-Sutherland compound SrCu2(BO3)2. The first part of the experiment aims to establish the Q-dependence, which will... -
Magnetic Excitations of a Model Quantum Spin Ladder
(C5H12N)2CuBr4 is the best realisation found to date of an antiferromagnetic quantum spin ladder in the strong coupling limit. This system displays an extremely rich phase... -
Magnetic excitations in the S=1/2 ferromagnetic semiconductor Lu2V2O7
Lu2V2O7 is a rare example of an S=1/2 pyrochlore. The fact that it is a ferromagnet with Tc=70 K belies the fact that it has some truly remarkable properties. These include the... -
Magnon decay below the critical field in the S=1/2 Heisenberg antiferromagnet...
The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model quantum magnets. This is in part due to its intrinsic interest but also to... -

Magnetic fluctuations in the ferromagnetic Mott insulator Yb2V2O7
We have investigated spin excitations in Lu2V2O7 on MERLIN in this cycle and it would be interesting to investigate how the spin excitations change when one have magnetic ion in... -
Quasielastic scattering in stuffed spin ices: defects or low lying singlets?
The subjects of this proposal, Ho2+xTi2-xO7-x/2, are brand new materials1 related to Ho2Ti2O7, a spin ice2,3. They have the remarkable property of remaining disordered at very...
