Tuning B-B exchange in the R2MnMn(Mn4-xTix)O12 quadruple perovskite manganites
For the RMn3O6 manganites, we have shown that tuning A-B exchange, by choice of A-site cation or by doping magnetic impurities, gives rise to dramatically different magnetic... -
Magnetic structure determination of PrMn7O12 polymorphs
The AA'$3$Mn$_4$O${12}$ family of manganites with quadruple perovskite structure has recently attracted a lot of interest as a disorder-free model system for many of the... -
Structure-property relation in integer-spin quantum magnets
Our objective is to determine how changes in symmetry affect the magnetic ground state of spin-1 magnets. Low-dimensional S=1 systems are believed to support rich phase diagrams... -
Pressure effect on high-temperature multiferroic CuO studied by a single crys...
We propose to perform neutron diffraction experiment under high pressure condition, using a single crystal of CuO on WISH beamline. This monoxide is known as a multiferroic... -
Crystal and magnetic structures of polar Co2ScSbO6 oxides
Polar A2BSbO6 oxides with the Ni3TeO6 structure type (space group R3) are being investigated as possible ferroelectrics. Ni2ScSbO6 is reported to have incommensurate helical... -
Origin of giant ferroelectricity in perovskite-type Mn2O3
Perovskite-type compounds can be both very simple and tremendously complex. Remarkably, even binary perovskite-type compounds may exhibit high level of complexity that leads to... -
Correlation of structural and magnetic properties in oxides containing 1-D ch...
Purely ferromagnetic (FM) oxides are uncommon but we recently reported FM behaviour in a mineral induced by quite small magnetic fields. This ability relates to the presence of... -
Investigation of the phase diagram of Ba1-xNaxTi2Sb2O (WISH portion)
We propose using WISH and HRPD to examine the structure of the Ba1-xNaxTi2Sb2O phase diagram as a function of temperature. The primary goals are the determination of the... -
Magnetism and electronic structure of 3d 5d double perovskites
Emerging technologies require increasingly unusual functional materials and so understanding the origins of complex magnetic and electronic behaviour, and how these can be... -
Investigations of some ruthenates with extended superexchange pathways
The superexchange interaction - in which the intervening oxygen mediates magnetism between two partially filled d shells- is well described by the semi-empirical... -
Magnetic structure of pyrochlore irridate Y2Ir2O7
We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed... -

We aim to study select samples of hole and electron doped (A,A')(Fe,B)2As2 (A=Ba, Sr, or Ca; A'=Na, K and B=Co, Ni, or Pt) iron pnictides. These materials exhibit robust... -
Probing the nuclear and magnetic structure of a complex ferromagnetic semicon...
Understanding the structures of complex materials is key understanding their properties. Here we wish to determine the structure, both atomic and magnetic, of a complex... -
Devil's staircase in the Kondo lattice semimetal CeSbSe
We propose to determine the magnetic structure of a new material, CeSbSe, at zero field and in magnetic fields up to 3 T, using the unique capabilities of the WISH...
