This dataset contains measurements of dissolved organic carbon (DOC), dissolved inorganic nitrogen (DIN) and soluble reactive phosphorus (SRP) concentrations, and dissolved...

Understanding the structures of complex materials is key understanding their properties. Here we wish to determine the structure, both atomic and magnetic, of a complex...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

The hexagonal perovskites make up a large and technologically useful class of oxide materials, with applications as diverse as dielectric resonators for mobile phones and fuel...

LaFeAs1-xPxO has recently been proposed to display unusual properties as a function of P doping with two distinct superconducting (SC) domes separated by a possible AFM phase as...

The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,...

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....

In the coming year, we plan to build upon the success of last cycle by carrying out more hydrocarbon studies of this porous material NOTT-300 and one of its iso-structural...

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...

In this proposal, we would like to propose to perform neutron diffraction experiments on the powder samples of the frustrated antiferromagnets AFeO2 (A=Cu and Ag) using WISH. In...

A recent addition to the list of emergent materials is the ReBaCo4O7+delta family of compounds. Indeed, due to the magnitude of their oxygen uptake and release capability, they...

We propose to use WISH to examine whether a transition between different spiral antiferromagnetic structures in zero magnetic field is the key to tricriticality at finite fields...

In recent years there has been a large interest in geometrically frustrated magnetic systems, especially those with spins interacting on two-dimensional triangular lattices...

The National Physical Laboratory (NPL) and the WISH instrument team has worked together to enable simultaneous real-time high resolution (powder and single crystal) neutron...

Test of the NIMS low temperature pressure cell on WISH.

Our muSR study on Ce(Os1-xFex)2Al10 with x=0.4, which reveals long range magnetic ordering below 24K from the heat capacity, shows unexpected temperature dependence. The muSR...

Oxides of 5d elements such as Ir and Os have been attracting much attention as candidates to realize novel types of electronic ground states stabilized by the strong spin orbit...

Zeolites are porous crystals that make it possible to generate regularly arrayed alkali-metal nanoclusters. Potassium clusters arrayed in zeolite A show ferromagnetism below 7 K...

The late first row transition metal monoxides are the canonical antiferromagnets. Their magnetic structures were first determined many decades ago but contemporary studies have...
