Determination of the magnetic interactions of low-dimensional binary metal th...
Magnetic molecular framework materials, where the magnetic metal centres are linked together by molecules rather than single atoms, are a very exciting class of materials, as... -
Fractionalized excitations in the zigzag pseudospin-1/2 quantum chain compoun...
One-dimensional (1D) S = 1/2 spin chains are a subject of long-standing interest, because conventional long-range ordering can be prevented and novel Luttinger-liquid phase may... -
Spin wave excitations in the 2D honeycomb ferromagnets
Graphene is the single layer of honeycomb-shaped carbon network, for which 2010 Nobel Prize in Physics was awarded thanks to its novel electronic properties. One of such... -
High Temperature study of BaFe2As2
Recent unpublished data collected at MAPS by our group revealed that the spin wave dispersion of the Ba(122) parent differ significantly from Ca(122). In Ba(122) there is a... -
Excitations in an orbitally dimerized spin S=1 honeycomb antiferromagnet
Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold... -
The study of spin excitations in superconducting LiFeAs
The spin excitations in superconducting LiFeAs have been found evolved from incommensurate peaks to commensurate peak at low energy. But the spin resonance is still not clear in... -
Spin fluctuations in the triangular antiferromagnet beta-NaMnO2
We propose to perform a neutron inelastic scattering study on the anisotropic triangular lattice system beta-NaMnO2. This work will be an extension of our previous study on... -
Unravelling the origin of high-temperature magnetic bistability in dysprosoce...
In the last 25 years the highest blocking temperature TB achieved for the best performing molecular nanomagnets has only reached few K. The situation has recently changed... -
Magnetic excitation spectra in the field induced quantum phases of the quasi-...
We propose to investigate the magnetic excitation spectra in the three accessible magnetic ordered phases of the quasi-1D S-1/2 Ising-like antiferromagnet SrCo2V2O8 by single... -
Study of frustration and the anomalous Hall effect in Fe3Sn2
We have found unusual and promising Hall effect behaviour in the alloy Fe3Sn2 at 300K. Fe3Sn2 is predominantly ferromagnetic, however, our neutron diffraction data indicate that... -
Study of the S(Q, w) map of propane/propene adsorbed on non-charged ITQ-29 Ze...
Zeolites are perhaps the most successful microporous materials used for catalysis and separation processes in refineries and chemical industries[1-3]. This is due to the... -
Excitations of a solitonic lattice in the multiferroic material TbFeO3
The multiferroic system TbFeO3 undergoes magnetic transitions at 8.5 and 3 K, and with further modification in applied fields leading to a complex H-T phase diagram. At a... -
Magnetic excitation of Ca2RuO4 in pressure induced ferromagnetic phase
Recently, a novel type of Bose-Einstein condensation (BEC) of spin-orbit excitons has been proposed in Mott insulator Ca2RuO4. In the recent INS study, we have observed... -
Resonant Spin Excitation in Single Crystal of Ba0.3K0.7Fe2As2
We recently observed a resonant spin excitation in Ba1-xKxFe2As2 (x=0.4), one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates... -
Investigation of giant crystal electric field (CEF) splitting in CeIr3Si2
CeIr3Si2 exhibits highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall CEF splitting of the J=5/2 ground multiplet of... -
Spin dynamics of quantum spin liquid state in CaCu3(OH)6Cl2・0.6H2O
Recently we have succeeded in synthesizing a new kagome material, CaCu3(OH)6Cl2 0.6H2O. Single crystal X-ray measurements revealed that no site disorder between Ca and Cu sites... -
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,... -

Phonon measurements of the incommensurate phase transition in Åkermanite
The proposal is to measure the inelastic scattering from a single crystal of Åkermanite on cooling towards and through the incommensurate phase transition at 358 K. There are...
