The layered NaMnO2 is challenging as it is an experimental realization of a two-dimensional spin-2, spatially anisotropic triangular lattice, where the interplay of temperature...

Our previous neutron scattering on C14 Laves phase compounds Nb1-yFe2+y revealed that a spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical...

We propose to use a pulsed magnet system tried and tested at several neutron and synchrotron facilities in conjunction with the new high flux diffractometer WISH to perform the...

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...

Very recently, string states have been identified for the first time in antiferromagnetic Heisenberg-Ising chain SrCo2V2O8 in longitudinal magnetic fields using high-resolution...

Ammonia borane (AB) is one of the most promising hydrogen storage materials. We have extensively studied the low temperature behaviour of this material This proposal asks for 3...

In a previous WISH experiment, we have succeeded in determining the incommensurate cycloidal magnetic structure of AgFeO2, which induces a ferroelectric polarization[1]....

We propose a study of the magnetic structure of isotopically enriched Gd2Ti2O7. We have successfully grown and characterised large single crystals using low-absorption 160Gd. In...

For several years, we have been studying the thermodynamics of the metamagnetic phase transition in CoMnSi and substituted versions. Our motivation has been that 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...

Cu2OSeO3 belongs to a family of magnetic crystals that displays unique properties of a whirlpool like vortex of magnetic moments (skyrmions) in a small range of temperature and...

We have recently observed unusual magnetostrictive behaviour in Bi0.5La0.5FeO3 (BLFO), a phenomenon which is not present in either solid solution end member. This proposal seeks...

Magnetic cooling promises efficiency savings at room temperature but requires rapid cycling of a magnetic refrigerant in a magnetic field. Refrigerants with first order...

Lu2V2O7 is a rare example of an S=1/2 pyrochlore. The fact that it is a ferromagnet with Tc=70 K belies the fact that it has some truly remarkable properties. These include the...

Hertbertsmithite ZnCu3(OH)6Cl2 is a model S =1/2 kagome antiferromagnet, received much attention last years. From recent studies a sign of a nearby quantum phase transition...

Non-coplanar magnetic orders in metallic helimagnets have been of great interest since the discovery of a vortex-like spin-swirling object called "skyrmion" and the resulting...

We propose to perform neutron diffraction experiments under high-pressure on multiferroic TbMnO3 using WISH in combination with hybrid-anvil-type high-pressure device. Recently,...

Determination of the position of hydrogen in inorganic materials such as zeolites, coordination compounds, H2 storage materials, energy materials, organometallics etc is a...

We propose to perform neutron diffraction experiments under high-pressure and magnetic field condition for multiferroic DyMnO3, using WISH beamline in combination with...

The study of skyrmion (magnetic vortex) lattice formation below ~30 K in chiral magnet MnSi has gotten very good attention in the recent times. Few of the key questions concerns...
