Transition metal pyrovanadate M2V2O7 (M = Ni, Co, Mn) exist with a great variety of crystal structures, which are reflected in the richness of their physical properties....

SrCuTe2O6 is a quantum magnet featuring spin-1/2 magnetic ions that are coupled intoantiferromagnetic chains with frustrated interchain coupling. An ideal...

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...

This project lies on the study of multiferroic materials in which both electric dipole order and magnetic order coexist. These materials are of the potential for new technology...

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]....

When isolated spin clusters are weakly coupled to each other, zero-dimensional quantum and three-dimensional collective magnetism concomitantly occur. This is envisioned in the...

We have synthesized the polycrystalline R2BaCuO5 (R = Dy & Ho) and studied its physical properties. Indeed, both the studied compounds exhibit the polarization below rare...

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

The layered compound Na2Co2TeO6 is a model honeycomb compound having a zigzag antiferromagnetic (AFM) ground state. Na2Co2TeO6 poses a rich magnetic phase diagram in the H-T...

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...

Lead based oxides are wildly used in material science in order to obtain non-centrosymmetric structures that eventually lead to polar or piezoelectric distortion, which coupled...
