Dilution of the Near-Kagome Compound Vesignieite
Vesignieite, Cu3VBa2O8(OH)2, is one of very few materials approximating a kagome spin-1/2 Heisenberg antiferromagnet, a model that is the ideal setting for novel quantum spin... -
Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
Kagome quantum spin liquids - The case of Vesignieite
We aim to explore the groundstate of a new near-perfect S=1/2 kagome antiferromagnetic (KAFM) system using MuSR at the lowest possible temperatures. The title compound is... -
Investigation of magnetic phase coexistence and determination of magnetic pha...
The solid solution Mn(1-x)Fe(x)WO4 exhibits complex antiferromagnetic order with coexistence of commensurate and incommensurate magnetic structures. Furthermore, the MnWO4 end... -
Study of frustration and the anomalous Hall effect in Fe3Sn2
We have found unusual and promising Hall effect behaviour in the alloy Fe3Sn2 at 300K. Fe3Sn2 is predominantly ferromagnetic, however, our neutron diffraction data indicate that... -
Investigating the magnetism in the potential multiferroics Pb3TeCo3B2O14 (B =...
We propose to use WISH to perform high resolution diffraction measurements using a fine temperature step size on powder Pb3TeCo3B2O14 (B=V,P). These measurements are crucial to... -
Magnetic structure of beta-MnRu
We have recently succeeded in isolating single crystals of Beta-MnRu, which we know propose to study using the WISH diffractometer. Previous powder measurements of beta-MnRu... -
Magnetic and nuclear structure in a new S=0.5 kagome antiferromagnet, SrCu3V2...
S=0.5 kagome antiferromagnets (KAFM) provide the most promising model system for realising the Resonating Valence Bond (RVB) state. Several S=0.5 KAFM materials are currently... -
Crystal Structures of Multiferroic MnWO4: HRPD
Multiferroic materials are rare and exceptional: they are ferroelectric and ferromagnetic in the same phase and these two properties can couple. Recently, materials with complex... -
Magnetic ordering and an extraordinary anomalous Hall effect in the itinerant...
-Fe3Sn2 is a rare example of a ferromagnetic metal. It features a giant Anomalous Hall Effect (AHE) at room temperature that makes it a candidate material for spintronics... -
Quantum spin liquids: beyond Herbertsmithite
We aim at exploring the ground state of new Cu2+ S=1/2 kagome compounds, isomorphic to the now-celebrated Herbertsmithite, namely CdCu3(OH)6Cl2 and MgCu3(OH)6Cl2. Due to the... -
Quasielastic scattering in stuffed spin ices: defects or low lying singlets?
The subjects of this proposal, Ho2+xTi2-xO7-x/2, are brand new materials1 related to Ho2Ti2O7, a spin ice2,3. They have the remarkable property of remaining disordered at very... -
Understanding the Earth's Core-Mantle Boundary: Crystal and Magnetic Structur...
The physical properties of the post-perovskite phase of MgSiO3 control the dynamics of the lower thermal boundary layer of the Earth¿s mantle, but many of these properties... -
Investigation of the re-entrant spin glass component and the anomalous Hall e...
Fe3Sn2 is a rare example of an itinerant frustrated ferromagnet (Tc = 640K), with a non-collinear spin structure. It shows a large anomalous Hall resistivity in a low field of...
