Polaron-mediated colossal magneto-resistance (CMR) was predicted decades ago but never been experimentally established unambigously, despite the 'universal' existence of...

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...

We have discovered a novel type of quantum spin liquid in a hexagonal lattice of Ru5+ dimers in Ba3ZnRu2O9, where any traces of the Curie tail or glassy behavior have not been...

The nature of the ground state of the spin-1/2 kagome lattice antiferromagnet remains an important question. Cu(1,3-bdc) is a hybrid organometallic compound featuring S=1/2 Cu2+...

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

Pure Ca3Co2O6 is a model system of ferromagnetic Ising chains arranged antiferromagnetically on a triangular net. Furthermore this system has aroused great interest because at...

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...

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...

New ionic liquids made of diamagnetic cations and anions consisting of d- and f- transition metal complexes are gaining increasing recognition because of their marked...

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...

Multiferroics have been highly topical in the past decade due to potential applications in, amongst others, data storage. Cr2O3 was the first linear magnetoelectric compound,...

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

The inter-metallic B20 compound MnSi is of great interest as a magnetic model system exhibiting helical spin ordering and topologically non-trivial spin correlations. The...

The two dimensional Heisenberg antiferromagnet on a square lattice is one of the most studied model in quantum magnetism . This is in part due to its intrinsic interest but also...

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...

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...

Our neutron study on YbAl3C3 reveals the presence of two well defined magnetic excitations at 1.5 and 3 meV at 4 K due to spin-dimer formation. Interestingly the specific heat...
