SrCuTe2O6 is a quantum magnet featuring spin-1/2 magnetic ions that are coupled intoantiferromagnetic chains with frustrated interchain coupling. An ideal... -
Neutron Diffraction Studies on CaCrFe3As3 compound
We propose to obtain 3 days of beam time on SXD equipped with its new top-loading CCR to analyze CaCrFe3As3 single crystals at different temperatures 10 K, 100 K and 300 K (the... -
Single Crystal Investigations of Polymorphism and Disorder in CH3NH3PbI3
Photovoltaics are one of the most promising technologies for meeting future energy requirements. CH3NH3PbI3 was first used in a solar cell in 2009, which gave an efficiency of... -
Determination of the low temperature crystal structure of Fe3O4
The aim of this proposal is to determine the crystal structure of Fe3O4 (magnetite) in its low temperature phase below the Verwey transition. Despite a considerable amount of... -

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... -
High resolution measurement of mode Grueneisen parameters in the negative the...
ZrW2O8 is the classic example of a material exhibiting negative thermal expansion (NTE), i.e. lattice shrinkage on warming. The origin of this behaviour has been controversial... -
High precision measurements of the spin wave dispersion in 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... -
Phonons from diffraction and normal mode analysis in HMT
With the overall aim of extending the information derivable in a neutron single crystal diffraction experiment beyond the static structure, we are proposing to perform a... -
Magnetic structure of noncentrosymmetric CeZnAl3
The Ce-based materials CeTX3 (T=transition metal, X= Si, Ge, Al) crystallizing in the noncentrosymmetric BaNiSn3-type structure, have been found to display a wealth of novel... -
A structural study of titanium tellurite glasses
Tellurite glasses exhibit strong non-linear properties which are related to the asymmetric environment of the Te atom. The non-linear optical effects are strongest when the Te... -

The ground state of the single layer half-doped manganite Pr0.5Ca1.5MnO4 has the canonical CE antiferromagnetic charge- and orbitally-ordered (CO-OO) structure characteristic of... -
Two-Dimensional Incommensurate Modulation in Melilite
We have prepared large single crystals of the melilite electroltyes Ln1+xCaxGa3O7+d; (Ln = La and Nd; x = 0 and 0.5) using a floating zone mirror furnace. We have characterised... -
Local field orientation and correlation length in the metal-organic perovskit...
In the metal-organic perovskite copper guanidinium formate, correlated Jahn-Teller distortion gives rise to a 1D magnetic structure made up of Heisenberg antiferromagnetic... -
The exploration of spin waves and magnetic interactions in BaFe12O19
As a member of the large hexagonal ferrite families, M-type barium ferrite BaFe12O19 has been largely investigated by the researchers owing to its rich properties. Recently, a... -
