Search for magnetic long-range order in a spin-liquid candidate K2Ni2(SO4)3
We recently synthesised a new compound, K2Ni2(SO4)3, that allows the existence of non-trivial topologicalphases such as skyrmions. Specific heat measurements show the existence... -
Probing Magnetic Order in 1D Holmium Magnetocaloric Frameworks
Lanthanide coordination frameworks containing polyatomic anions are attracting increasing attention for low dimensional magnetism, which appears to be linked to improved... -
Quantum magnetism in lanthanide gallium garnet magnetocaloric materials
Geometrically frustrated lanthanide gallium garnets find practical applications as low temperature magnetocalorics, but the competing interactions in these materials may give... -
Defects and monopole dynamics in spin ice
We have determined the defect structure of oxygen-depleted Y2Ti2O7 using diffuse neutron scattering, and we find that these oxygen vacancies are also the dominant defects in... -
Neutron diffraction study of the structures and magnetic properties of Halden...
A large variety of exotic magnetic structure and relevant magnetic properties is observed in honeycomb layered oxides. Recently Koo et al. showed two magnetic contributions i.e.... -
Dipolar Ordering of a High Spin Molecular Nanomagnet
Systems with antiferromagnetic ordering that is driven predominantly by dipolar interactions are very rare, as the dipolar interaction is inherently weak compared to the... -
Diffuse magnetic scattering in the Pyrochlore magnet Sm2Ti2O7
Rare-earth Pyrochlores of the form A2B2O7 display a diverse set of physical phenomena emanating from the strong geometrical frustration experienced by magnetic moments on this... -
The phase diagram of the spin-density-wave metamagnet Sr3Ru2O7
Sr3Ru2O7 is an unusual layered oxide metamagnetic metal. It has been know for some time that the application of a large magnetic field (~8 T) perpendicular to the RuO2 planes... -
Exploring low dimensional magnetism in lanthanide metaborates Ln(BO2)3
Lanthanide metaborates Ln(BO2)3 [Ln = La - Tb] form a monoclinic structure with 1d chains of magnetic Ln3+. Their magnetic properties have not been investigated before and they... -
Magnetic order in Er2Si2O7
We propose to use neutron diffraction to establish the magnetic structure of D-type of Er2Si2O7 in zero field first with a view of extending the measurements to an applied field... -
Dy3Mg2Sb3O14 - a 2D Kagome lattice with Classical Ising Spins
Dy3Mg2Sb3O14 forms a layered structure with magnetic Dy3+ ions forming sheets of corner sharing triangles, called a Kagome lattice. The Ising magnetic moments are constrained to... -
Magnetic order in a pyrochlore iridate
Iridium oxides are of interest because many novel magnetic phases have been predicted in crystals, depending on the geometry of the crystal lattice. Our proposal concerns one... -
Solving the antiferromagnetic structure of Gd3Al5O12.
This proposal would like to map the diffraction patterns of Gd3Al5Gd12 (GAG) using the high flux diffraction instrument WISH. It is of great interest to solve the magnetic... -
First experiment with a pulsed field magnet at ISIS or how to break the 15T b...
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...
