Skyrmion-like structures induced by copper doping in multiferroic CaCuxMn7-xO12
Multiferroic CaMn7O12 possesses giant magnetically induced ferroelectricity at relatively high temperatures - key properties for technological application. X-ray and neutron... -
The charge-ordered superstructure of YbFe2O4
There has been much recent interest in the so-called ¿novel¿ or ¿type-II¿ multiferroics, in which electrical polarisation appears at the onset of a particular type of magnetic... -
The intermediate stages of hydrogen disorder to order phase transitions in ice
In recent years, our team has discovered three new phases of ice: ices XIII, XIV and XV. On the basis of calorimetric data and some limited diffraction data collected on GEM we... -
Magnetic phase diagram of multiferroic GdMn2O5
In the last five years, we have carried out a comprehensive study of the family of REMn2O5 multiferroics by neutron and X-ray magnetic scattering, providing details about the... -
Subtle magnetic phase transitions in multiferroic BiFeO3
This experiment seeks to probe the magnetic structure of multiferroic BiFeO3 and its evolution on lowering temperature, with the specific aim of identifying magneto-structural... -
3D neutron TOF diffraction imaging
We propose to use SXD for mapping the crystallographic phases in an extended 3D benchmark object. The phase distribution will be reconstructed using a geometrical aberration... -
Charge disproportionation and structural modulation in multiferroic CaMn7O12
Multiferroic materials in which strongly coupled magnetic and ferroelectric order parameters coexist attract considerable interest. Below 90 K, CaMn7O12 possesses the largest... -
Long-range magnetism in spin, charge, and orbital ordered Pb3Mn7O15
Manganese oxides have attracted great interest in solid-state physics research owing to the diverse range of electronic ordering phenomena. Pb3Mn7O15 is a relatively... -
Magnetic structure of the new chiral magnetoelectric Sb2MnO6
Magnetoelectric multiferroics have been recently the focus of a significant research effort. The experiment that we propose explores a new class of "magnetochiral" systems,...
