Description | The key findings are well documented in the numerous publications which have arisen from the award, all in internationally leading journals. The overarching theme is that the combination of strong spin-orbit coupling and electron correlations can lead to novel electronic and magnetic states of matter. Revealing and understanding these states of matter using experimental techniques based on the exploitation and development of facilities for neutron and X-ray scattering has been a key objective of the grant. For example, Ca2RuO4 has attracted considerable attention in recent years as the Mott-insulating analogue of the unconventional superconductor Sr2RuO4. Using a combination of X-ray and neutron scattering we have revealed how the magnetic and electronic structures evolve as a function of doping, thus allowing us to understand the origin of the metal insulating transition it displays. This work alone led to three papers - two in PRB and one in Nature Communications. |
Exploitation Route | Our work arising from this funding is beginning to attract considerable interest in the academic community, facilitating progress on the development and exploitation of novel electronic materials. |

Title | Data for "Spontaneous cycloidal order mediating a spin-reorientation transition in a polar metal" |
Description | Data for the manuscript "Spontaneous cycloidal order mediating a spin-reorientation transition in a polar metal" by C. D. Dashwood, L. S. I. Veiga, Q. Faure, J. G. Vale, D. G. Porter, S. P. Collins, P. Manuel, D. D. Khalyavin, F. Orlandi, R. S. Perry, R. D. Johnson, and D. F. McMorrow, Phys. Rev. B 102, 180410(R) (2020).All the data is provided in text files, each containing a single header line followed by the data. All temperatures are in Kelvin, magnetic field strengths in Tesla, angles in degrees, and resistances in Ohms.The parent folder contains the in-plane resistivity and powder XRD data.Neutron scattering data is contained in the "Neutron" folder, with each file labelled by the magnetic field strength and Bragg peak (commensurate peak "001" or incommensurate satellite peak "d01").Resonant x-ray scattering data is contained in the "X-ray" folder, under four subfolders for the azimuthal dependences ("Azi_deps"), energy dependences ("E_deps"), reciprocal space scans ("H_scans") and theta scans ("Th_scans"). Files in all the subfolders are labelled by the temperature and Bragg peak (commensurate peak "005" or incommensurate satellite peak "d05"), followed by further labels for the x-ray polarisation ("sig-sig" or "sig-pi"), azimuthal angle ("psi90" or "psi180") and absorption edge ("L2" or "L3"). The azimuthal dependences folder also contains a file "Parameters" with the fitted values of Ma and Mb (defined in the manuscript) and their errors. |
