We propose to perform high-resolution neutron diffraction on strained Ca3Ru2O7, a material in which electron correlations, spin-orbit coupling and crystal fields combine to...

We recently synthesised a new compound, K2Ni2(SO4)3, that allows the existence of non-trivial topologicalphases such as skyrmions. Specific heat measurements show the existence...

The f-electron metal Yb2Pt2Pb is best thought of as a one dimensional (1D) quantum spin chain system, despite the fact that the magnetic moments are large and anisotropic with...

We propose elastic neutron powder diffraction experiments on new perovskite antimonates (Ba,K)SbO3. Recently, we confirmed that heavily K doped antimonates become...

A better understanding of the magnetic excitation spectrum of LuFe2O4 is required to refine current models of the magnetoelectric coupling in this novel "electronic"...

There is a significant interest in the electronic and magnetic properties of the layered iridates owing to the variety of potential exotic phases of matter they exhibit. In...

Previous neutron studies of powdered Gd2Ti2O7 (GTO) have shown that despite it relative simplicity as an s-state Heisenberg antiferromagnet, the magnetic structure is a fairly...

Encouraged by many unconventional magnetic properties in the magnetically frustrated spin-chain compounds of the type A3MM'O6, we have recently synthesized a new member...

PbCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu2+ ions coupled by 3 interactions. The 1st neighbor interaction couples Cu2+ into isolated triangles, 2nd nearest...

Rare-earth orthoferrites (RFeO3) and orthochromates (RCrO3) exhibit canted antiferromagnetic structure with 3 different allowed spin configuration (SC)s.Temperature as well as...

We propose to test new apparatus for the magnetic neutron diffraction under uniaxial pressure on WISH diffractometer. The main feature of our apparatus is that the sample is not...

Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications. It is a ferrimagnetic spinel with the narrowest ferromagnetic resonance linewidth of any known...

Most optimally-doped high- Tc cuprate superconductors show a magnetic excitation (known as the 'resonance') at q=(pi,pi ) whose intensity increases sharply below Tc. This...

Ba2LuMoO6 is a rare example of an s = ½ undistorted fcc frustrated system, which displays no magnetic order above T = 2 K, and thus is an excellent experimental realisation of a...

New manganese-based double perovskites Mn2-xCaxFeReO6 have been synthesised at high pressure. Mn2FeReO6 has spin-active cations at all sites; S = 5/2 Mn2+, S = 5/2 Fe3+ and S =...

Geometrically frustrated antiferromagnet LuBaCo4O7 exhibits unusual competition between two low-temperature phases with orthorhombic and monoclinic symmetry. Depending on...

We have recently used INS to determine how a hydrogen pre-treatment stage of an iron based Fischer-Tropsch catalyst may modify catalytic performance. That work established how...

Superconductivity (SC) in unconventional superconductors is believed to be related to magnetism. However, in AyFe1.6+xSe2 (A = K, Rb, Cs) system discovered in late 2010, the SC...

This proposal is for time to search for predicted gas hydrates at high pressure. The results will provide insight into the factors governing the stability of the H-bonded...

Sr2RuO4 is a 2-D layered perovskite oxide metal which becomes superconducting below 1.5K. There is strong experimental evidence that the superconducting wavefunction is...
