The single ion crystal field ground state of Yb3+ in Yb2Ir2O7
The rare earth iridates, R2Ir2O7 have been intensely studied in recent years due to the unique behaviour of the magnetism on the iridium sites; a consequence of competition... -
Exploration of possible spin-charge ordered phases in La2-xBaxCoO4 (x=1/3 and...
This is a proposal to measure the magnetic spectrum of single crystal La2-xBaxCoO4 for the first time. The isostructural layered cobaltates with Sr and Ca instead of Ba have... -
Magnetic interactions of the room-temperature skyrmion material Co8Zn8Mn4
We propose an investigation of the spin-waves in the recently discovered room-temperature skyrmion material Co8Zn8Mn4. The ground state of Co8Zn8Mn4 is a very long wavelength... -
Unconventional superconductivity in quasi-1D K_2Cr_3As_3
Metallic systems with one-dimensional chain-like atomic structure can support unusual mechanisms for electron pairing leading to superconductivity. K_2Cr_3As_3 is one of a... -
Magnetic excitations in novel ferrimagnetic spinel ScMn2O4
Spinel oxides with the formula AB2O4, are an important structural family of materials which exhibit a large variety of interesting and industrially relevant properties. We have... -
Spin excitations in the paramagnetic phase of a charge-ordered bilayered mang...
In a previous experiment we measured the spin wave spectrum of the half-doped bilayer manganite Pr(Ca,Sr)2Mn2O7 in its spin, charge and orbital ordered phase. The data, which... -
2D vs. 3D ordering in CrCl3, a Heisenberg antiferromagnet on a honeycomb lattice
Van der Waals solids containing two-dimensional lattices of magnetic moments with only weak interlayer coupling have attracted significant scientific interest due to their... -
Weyl Points in the Magnetic Excitations of Er2Ti2O7
In the condensed matter community the last ten years have seen a revolution in our understanding of how topology influences the properties of solids. A famous example from the... -
Phonon dispersion and defects in pyrochlores
Pyrochlores exhibit a rich variety of exotic physical properties including fractionalization, topological order and emergent magnetic monopoles in the classical spin ices, and a...
