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...

Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This...

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 =...

In recent years, there has been a large research interest in noncentrosymmetric systems in part due to the exotic physics these systems display. Examples of chiral magnets...

We propose to fully explore the field induced magnetically ordered phase of copper-nitrate, Cu(NO3)2.2.5D2O, at temperatures below 0.13 K and in fields up to 5 T. The key aims...

Multiferroic materials, where there is a strong coupling between magnetic and electric order parameters, offer a route to novel voltage-controlled spintronics. Y-type...

We propose to investigate the field induced behaviour of ErB4 using WISH. ErB4 is an example of experimental realisation of the Shastry-Sutherland lattice, a frustrated lattice...

There is a growing need to reduce dependence on liquid He for cooling applications below 20 K. Magnetocalorics, which exhibit an entropically driven cooling effect in a cycled...

In BaDy2O4, the magnetic Dy3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, which gives rise to geometric...

Using high-temperature high-pressure synthetic methods we have recently prepared the new quadruple perovskite CaFe3Ti4O12. Curie-Weiss magnetic susceptibility and Mossbauer data...

One-dimensional (1D) or two-dimensional (2D) topologies between magnetic ions generally favour strong magnetic anisotropy and offer exotic fundamental states and other phenomena...

We have observed an interesting phenomenon of the destruction of long-range magnetic order in SrEr2O4 by a relatively modest applied magnetic field. For a field applied along...

We propose to probe the development of the magnetic correlations in SrTb2O4 using WISH neutron diffractometer. In a magnetic sense, SrTb2O4 consists of triangular zig-zag...

This proposal requests time to investigate the influence of an applied magnetic field on the oxyselenide Pr2O2Fe2OSe2. A metamagnetic transition involving ordering of Pr3+...

Test of the NIMS low temperature pressure cell on WISH.

Manganese based oxides are of great interest for both spintronic and multiferroic applications.Pb2MnO4 crystallizes in the acentric but non-polar space group P-421c which allows...

The 1D ferromagnetic coupling within the chains of Tb(HCO2)3 appears to play a key role in its greater magnetic cooling performance above 4 K, compared to Gd(HCO2)3. Furthermore...

Linarite is a natural mineral which displays a rich and complex phase diagram in applied fields up to 10 T for temperatures below 2.8 K. As a frustrated J1-J2 chain material,...

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...

Ferroelectricity in type-II multiferroics is induced by breaking of inversion symmetry by certain type of spin structure below the magnetic ordering temperature. Therefore, a...
