On the ninety degree perpendicular domain wall in FePt/FeRh thin films.
Magnetic structures with an out of plane magnetic moment can be found in the latest generation hard disk drive. Interactions between a material with controllable out of plane... -
Understanding negative compressibility in KMn[Ag(CN)2]3
Negative linear compressibility (NLC) is the phenomenon whereby at least one of the linear dimensions of a material actually expand under hydrostatic pressure. It is only... -
Structural distortions and magnetic ordering in oxygen depleted spin ice
Geometrical frustration in the spin ice material Dy2Ti2O7 leads to macroscopic degeneracy and the observation of magnetic diffuse neutron scattering down to the lowest... -
Neutron scattering study on dynamics of cytochrome c in MCM41
Studies of internal dynamics in the pico seconds timescale, of cyt c trapped in MCM-41, would allow the forms, geometry, amplitudes and time-dependence of the motions involved... -
Crystal and Magnetic Structures of Ba2BTeO6 (B=Cu, Ni, Zn)
Ba2CuTeO6 and Ba2NiTeO6 are compounds with structures related to that of the proposed spin liquid Ba3CuSb2O9. The space group and nature of the B-site ordering in Ba3CuSb2O9... -
Polarized neutron reflectormetry study of ultra-thin FeRh films.
FeRh in the CsCl structure is an interesting material with a tunable magnetostructural phase transition close to, or just above room temperature. On heating through the... -
Evolution of spin wave excitations of Mn3Sn in different magnetic ordered phases
Mn3Sn has very complex magnetic ordered phase, a clear magnetic phase transition happens at T=~280K accompanied by the vanishing of AHE.For our Mn3Sn crystal grown by flux... -
In-situ High Temperature Studies of BiFeO3 in a Stabilising Oxygen Atmosphere
The drive to find novel materials for applications such as data storage has led to a resurgence in research into multiferroic materials. Bismuth ferrite is the most widely... -
Anomalous elasticity in negative thermal expansion materials
Recent experimental work on the negative thermal expansion material Zn(CN)2 has shown that the elastic stiffness is anomalously reduced on compression. That is, if B is the bulk... -
Neutron Diffraction Studies on YbCu4Ga8
We discovered a new compound YbCu4Ga8 and the available laboratory single crystal data shows that it crystallizes in the tetragonal system. The asymmetric unit contains one Yb... -
High resolution INS spectra of hydrocarbonaceous overlayers formed on novel m...
For the first time, the research team aim to use INS to characterise a series of new high specification methane reforming catalysts. The enhanced performance of these catalysts... -
Inelastic Spectroscopy of the Mobile Phase of Ammonia Borane
Ammonia borane (AB) is one of the most promising hydrogen storage materials. There has recently been work on a more mobile phase of AB (denoted AB*) which is formed (via the... -
Revisiting the magnetic structure of Yttrium Iron Garnet
Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications, having the narrowest ferromagnetic resonance linewidth of any known material. Despite decades... -
Diffuse scattering studies of squaric acid in an applied electric field
Organic ferroelectric compounds such as KH2PO4 and squaric acid, have attracted much interest in the past due to their potential in applications [1]. This interest has been... -
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... -
Thermochromism in N-salicylideneanilines
N-salicylidineanilines are known to show thermochromic behaviour, which is currently postulated to arise from an intramolecular proton shift between the keto and enol form as... -
The Dynamics of Breathing Metal-Organic Frameworks from Total Scattering
Metal-organic framework materials are a topical family of nanoporous solids that have potential applications in molecular storage, separation and catalysis. Some of these... -
Looking at the motion associated with the cation and their freezing in TEA(TC...
