Magnetic skyrmions are topologically protected spin structures with potential uses in low power devices. Cu2OSeO3 is a cubic material containing both skyrmions and other spin...

This proposal aims to explore a cheaper and more environmental-benign surfactant system for yielding efficient water/CO2 microemulsions. The new surfactants permit high...

YbNiSn is an Ising ferromagnet with non-colinear spins that undergoes a first order magnetic transition in low magnetic field (0.9 T). The transition is associated with strong...

The use of deuteration to overcome the difficulties associated with the incoherent scattering from hydrogen, is a well established technique. However, there are increasing...

We propose to measure the spin wave dispersion and intensities throughout the Brillouin zone of the single layer half-doped manganite Pr0.5Ca1.5MnO4, whose ground state has the...

The newly discovered AxFe2-ySe2 (A=K,Rb,Cs) compounds have attracted great interests because of their parent compounds are insulators instead of being metallic [2-6]....

Time of flight neutron diffraction (ToF-ND) is a powerful technique for the characterization of the micro-structural properties of the phases present in the sample. The Rietveld...

We propose to investigate the excitation spectrum of azurite in both zero field and applied fields up to 7T. Using inelastic neutrons on OSIRIS we hope to clearly resolve the...

We would like to study the time dependence of the dipole width, trapping rate, and detrapping rate with Al-Mg-Si-Cu alloys in the temperature range from 260 to 300 K by...

In SrYb2O4 the magnetic Yb3+ ions form sub-lattices of double chains running parallel to the crystallographic c-axis with frustrated first and second neighbour antiferromagnetic...

We measured temperature and time dependences of magnetization of Al-1.0%Zn-4.2%Mg (ZM14), Al-2.6%Zn-3.2%Mg (ZM33), and Al-4.1%Zn-1.1%Mg (ZM41) (at.%) alloys after various...

We propose to exploit the high resolution and well defined peak shape on HRPD to measure the evolution of peak profile shape at the early stages of deformation in stainless...

The proposed experiment forms a part of a joint study by M. Rahman, an ILL PhD thesis student, and J. Brokx, a CDT thesis student supported by ISIS. In the proposed experiment,...

Recently insulator-metal transition in Pr0.7Ca0.3MnO3 was observed at P = 0.5 GPa, implying a change in magnetic ground state, which was initially a pseudo-CE AFM one. In later...

We propose to investigate the resonance peak in superconducting CeCoIn5 as a function of applied field. Preliminary low resolution cold triple-axis data has been suggestive that...

We propose to study the high temperature structure of TiOCl where a pressure induced metal to insulator transition has been reported recently by Kuntscher et al.Due to our...

Though the beta and gamma forms of the simplest amino acid, glycine, yield a variety of different phases on application of pressure, Raman data suggest that the most common...

In SrHo2O4, the Ho3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, this gives rise to geometric...

To understand this novel ground state of CeCuAl3, we have carried out low and high-energies inelastic neutron scattering (INS) measurements using the IRIS and HET spectrometers....
