Neutron Spin resonance in the Fe-based silicide superconductor LaFeSiH
The iron-based superconductors (Fe-SC) are one of the most active and challenging topics in condensed matter physics. Very recently some of us (F. Bernardini et al.) have... -
Effect of oxygen vacancies on the phonon dispersion of pyrochlores
The frustrated magnetism of pyrochlores makes them candidates for applications in magnetic cooling and scientific instrumentation, and the proposal that they can be used to... -
Crystal electric field in the zigzag pseudospin-1/2 quantum chain compound Pr...
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... -
Resonant Spin Excitation in Single Crystal of Ba0.8K0.2Fe2As2
We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the... -
Rattling modes in new thermoelectrics
NaxCoO2 has an exceptional combination of thermoelectric properties, including low thermal conductivity, and it is currently under consideration for use in power recovery and as... -
Magnetic excitations and Orbital configuration in the vanadium spinel MgV2O4
The Vanadium spinels provide ideal systems to study the interactions between spin, lattice and orbital degrees of freedom. The magnetic V3+ ions are antiferromagnetically... -
Origin of spin excitation in single-layer cuprate Bi2201
We propose a measurement of spin excitation in heavily underdoped Bi2201 at MERLIN with intent to elucidate an origin of "hourglass" excitation in hole-doped cuprates. Recent... -

Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron... -
Spin excitations in the superconducting FeTe0.6Se0.4
The FeTe1-xSex series exhibits superconductivity over a broad range of doping. Previously we have made extensive neutron scattering measurements on superconducting x = 0.49 and... -
High Energy Spin Fluctuations in BaFe1.9Ni0.1As2
There has been much research into the recently discovered iron based superconductors, but so far only the magnetic excitations at low energy have been investigated. We propose... -
