YbNiSn is a Yb analogue of ferromagnetic superconductors URhGe and UCoGe. All materials share the same crystal structure, have similar Curie temperatures and a similar...

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

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...

Magnetic frustration occurs when nearest-neighbor competing interactions cannot be simultaneously satisfied. Pyrochlores, whose crystalline lattices form corner-sharing...

The material Cu(1,3-benzenedicarboxylate) (C8H4CuO4) features structurally perfect kagome lattice planes of spin-1/2 copper2+ ions, with the separated by organic linkers. High...

Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10...

Novel functionality in condensed matter physics is one of fastest developing fields, aiming for possible future applications including quantum computing, electronic devices and...

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,...

CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of...

Quantum spin liquids (QSL) are new and exotic states of matter that in 2 dimensions were proposed by Anderson to underpin the transition to unconventional superconductivity of...

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

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

Local magnetic interactions in lanthanide compounds have recently been shown to tune their entropically driven magnetocaloric effect (MCE), useful for magnetic coolants. In this...

Quantum spin liquid (QSL) is a novel state of matter where the spins are highly entangled with one another but fluctuate strongly down to zero temperature. It may be associated...

Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,...

CeFe2Al10 belongs to CeT2Al10 family (T: Ru, Os, Fe), which exhibits Kondo insulating behavior, with an unusual competition of strongly anisotropic crystal-field and exchange...

We propose to perform neutron diffraction experiments on single crystals, 3R-AgFeO2 and 2H-AgFeO2 on WISH. Recently, we have studied magnetic orderings and ferroelectricity of...

A previous CRISP measurement allows us to show for the first time using PNR a change in the response due to superconductivity in an Fe/Pb/Fe tri-layer sample. This type of...

Our objective is to determine how changes in symmetry affect the magnetic ground state of spin-1 magnets. Low-dimensional S=1 systems are believed to support rich phase diagrams...

The crystal structure of PrFe2Al8 consists of a network of Al which forms quasi cage-like structure where the Pr and the Fe form chains of atoms along the c-axis. We propose...
