We wish to construct a spectrometer on the Larmor instrument capable of resolving very small energy transfers between the neutron and the sample. To achieve this we will use a...

Magnetic frustration - the inability to mutually satisfy all magnetic interactions in a system - is the source of many interesting phenomena, including spin liquids and ices. In...

We have synthesized the polycrystalline R2BaCuO5 (R = Dy & Ho) and studied its physical properties. Indeed, both the studied compounds exhibit the polarization below rare...

Although the systems of choice for the study of electronic correlations have traditionally been 3d transition metal oxides, the interest has recently been extended to 4d and 5d...

Magnetic and orbital ordering in the manganese based perovskites has been of huge interest in solid-state physics since the 1950's. More recently, the family of AA′3Mn4O12...

The objective of this proposal is to solve the field-induced magnetic structure of a newly synthesized brownmillerite. Under normal conditions there are three different magnetic...

This proposal is to explore the evolution of magnetic ordering in two members of the homologous series CaFe2O4(FeO)n with n = 1, & 3, and to correlation the behaviour of the...

We propose to perform a neutron diffraction experiment under magnetic fields using a single crystal sample of multiferroic alpha-NaFeO2 on WISH beamline. Recently, we have...

Exotic electronic states are of great interest to fundamental science, such as the quantum spin-liquids (QSLs) which were theorised to behave like a sea of resonating spin...

The aim of the present proposal is to relate the macroscopic magnetic properties with the nuclear and magnetic structure of a series of Ni48Mn36In16-xSnx Heusler alloys. These...

The variant of the Hexagonal perovskite oxides are characterised by chains of trigonal prisms and octahedra, leading to a number of fascinating properties. Using resonant x-ray...

The superexchange interaction - in which the intervening oxygen mediates magnetism between two partially filled d shells- is well described by the semi-empirical...

The coupling between magnetic and electric degrees of freedom, in a single phase compound has been of intense research in recent literature, as the outcome would yield novel...

Emerging technologies require increasingly unusual functional materials and so understanding the origins of complex magnetic and electronic behaviour, and how these can be...

Three new doubly ordered perovskites NaYMWO6 (M=Mn, Co & Ni) have been synthesized by high pressure and high temperature. Analysis of room temperature laboratory X-ray...

We propose using WISH and HRPD to examine the structure of the Ba1-xNaxTi2Sb2O phase diagram as a function of temperature. The primary goals are the determination of the...

Perovskite-type compounds can be both very simple and tremendously complex. Remarkably, even binary perovskite-type compounds may exhibit high level of complexity that leads to...

Using NMR spectroscopy, the possible existence of a new magnetic state has been suggested to exist in LaFeAs1-xPxO (for x near 0.5); however, other groups failed to detect any...

We will probe the response of the magnetic and crystal structures of layered manganese oxide chalcogenides to the oxidation state and the local coordination environment of Mn....

We propose to perform neutron diffraction experiments on a powder sample of the frustrated triangular lattice antiferromagnets α-NaFeO2 under high-pressure up to 18 kbar...
