Quasi-elastic neutron studies of superstructure formation in battery materials
LixCoO2 is used extensively in portable batteries in laptops and mobile phones, but the scarcity of Li means that alternative materials are required. Structurally related... -
Crystallographic and Magnetic structures of PrMn7O12
The study of novel manganites, where the tailoring of the Mn formal valence state on the B site is done by the ordering of different cations on the A site of the ABO3 (B:Mn)... -
Incommensurate magnetic fluctuation in KFe2As2
The debate whether interband or intraband scattering is crucial for Fe-based superconductors is not settled down yet. Investigation a system with completely missing electron... -
4f electronic states of the filled skutterudite compound PrFe4Sb12 synthesize...
Crystals of the filled skutterudite PrFe4Sb12 with the 73~87% Pr-site filling fractions prepared under ambient pressure show some magnetic ordering around 5 K and their... -
Search for Neutron Spin Resonance and High Energy Spin Excitations in Exotic ...
Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,... -
Time reversal symmetry breaking in superconducting PrOs4Sb12 and its alloys
In 2005 we carried out muon spin relaxation (muSR) experiments in Pr(Os1-xRux)4Sb12 alloys at KEK, Tsukuba, Japan, to investigate the time-reversal symmetry breaking found in... -
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... -
Understanding anaesthetics: Ethanol partitioning into lipid membranes, effect...
Ethanol plays an important role in the human metabolism. It is in particular known to act as a drug enhancer by increasing trans-membrane permeability, and as an anesthetic.... -
Magnons and electromagnons in a magnetic field induced collinear commensurate...
In this proposal, we would like to suggest inelastic neutron scattering measurement on a single-crystal sample of a frustrated antiferromagnet CuFeO2 under applied magnetic... -
Pressure-dependence of the anisotropic exchange interactions in two closely r...
There are no magneto-structural correlations for clusters containing transition metal ions with non-zero orbital angular momentum in the ground state. Octahedrally coordinated... -
Spin-Lattice coupling in Frustrated Triangular Lattice Antiferromagnet AFeO2 ...
Back up experiment to fill gap in the schedule if beamtime is available -
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... -
Superconductivity induced changes in the ferromangetic order of Y(1-x)PrxBa2C...
By polarized neutron reflectometry we want to investigate the magnetic field profile in Y(1-x)PrxBa2Cu3O7/La(2/3)Ca(1/3)MnO3 high-Tc superconductor/ferromagnet superlattices. In... -
Direct Measurement of Spin Hamiltonian in an Organometallic S=1/2 Antiferroma...
The nature of the ground state of the spin-1/2 kagome lattice antiferromagnet remains an important question. Cu(1,3-bdc) is a hybrid organometallic compound featuring S=1/2 Cu2+... -
Superconductivity and critical spin fluctuations
In a successful recent experiment on IN5 (ILL), we have been able to show that in contrast to commonly accepted wisdom, the excitation gap in nearly optimally doped... -
Magnetic excitation in O2 supercrystal realized in nanoporous compound
We propose to perform neutron scattering experiment in a new field of science, magnetic O2 molecule supercrystal realized in nanoporous compound. In our previous work on...
