Understanding the barocaloric effect in Mn3NiN using inelastic neutron scatte...
Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric... -
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... -
High Energy Spin Excitations in Overdoped Superconducting BaFe1.85Ni0.15As2
The recent discovered iron pnictide superconductor which shows a transition temperature up to 50K has drawn much attention in the community. There are indications that... -
Q dependence of the low energy magnetic fluctuations in Intermediate Valence ...
A strong Q-dependence of the magnetic response at characteristic energy of EK~kBTK (TK is a Kondo temperature) has been observed in recent inelastic neutron scattering studies... -
Explore the spectrum of spin excitations in non-superconducting BaFe1.8Ni0.1C...
Recently, our neutron scattering experiments on electron doped BaFe2-xNixAs2 and hole doped Ba1-xKxFe2As2 suggest that the presence of both high-energy spin excitations giving... -
Spin gap opening associated with an extraordinary magnetovolume effect in som...
We have discovered an unusual magnetovolume effect in the 6H-perovskite oxides Ba3BiIr2O9 and Ba3BiRu2O9. These compounds contain isolated face-sharing bi-octahedral dimers... -
Study of the Hybridization Gap in the Topological Insulator YbB6
Topological insulators (TIs) are a new quantum state of matter which have bulk insulation but topologically protected metallic surface states. Initially, the TI state was... -
Is magnetic frustration behind the tetragonal-to-orthorhombic transition in t...
It has been argued that the tetragonal-to-orthorhombic structural transition found in all the parent phases of the Fe-pnictide superconductors is driven by frustration, and... -
Spin gap and possible spin-dimer formation in Ce(Os1-xFex)2Al10 (X=0 to 1)
Our neutron study using MARI/MERLIN on Ce(Ru1-xFex) 2Al10 reveals very interesting magnetic excitations and a manuscript is ready to submit to PRB. In x=0 (TN=27 K) a... -

Spin excitations of detwinned BaFe2As2
Although spin excitations in BaFe2As2 are thought spin-wave excitations and the excitation will locate at antiferromagnetic vector (1 0) only for a detwinned sample, the real... -
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... -
High-energy spin excitations in the optimally doped Ba0.67K0.33Fe2As2
From our previous data on BaFe2As2 and BaFe1.9Ni0.1As2, one may assume that the superconductivity only affects the low energy excitations. But for Ba0.67K0.33Fe2As2, the doping... -
High energy spin excitations detwinned SrFe2As2 single crystals
We are proposing to use inelastic neutron scattering to map out the spin excitation in 100% detwinned SrFe2As2 single crystals. We want to sort out how the anisotropic magnetic... -

Search for incommensurate spin excitation in BaFe1.904Ni0.096As2
Motivated by the observation of incommensure magnetic order in Ba(Fe1-xCox)2As2, we have recently grown BaFe2-xNixAs2 crystals with systematic electron doping level especially... -
Magnetic excitation in triangular latticce antiferromagnet alpha-CaCr2O4
The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different... -
Spin excitations in overdoped BaFe1.82Ni0.18As2
The relationship between spin fluctuations and superconductivity is an important issue in condensed matter physics. Part of evidence suggesting direct correlation between spin...
