Fishing for a new magnetic phase in the Pr1-xCaxMnO3 manganites phase diagram
Based on old data and the recent litterature, we suspect the existence of a poorly documented low temperature magnetic phase transition (T<30K) in colossal magnetoresitve... -
Investigations of some potentially multiferroic/magnetoelectric rare earth ta...
Multiferroics - where ferroelectric and magnetic orders co-exist - continue to be of technological and scientific importance, and of particular interest are the improper... -
Possible Magnetic new Fermions in Materials with the Pyrite Crystal Structure
In oder to understand our universe, we built large research facilities such as the LHC in Switzerland, which can be used to find new particles. In the solid state, such... -
Antiferromagnetic domain manipulation in hematite thin films studied by neutr...
We propose to study the antiferromagnetic (AFM) domain structure of 100 nm thick Fe2O3 thin films using WISH. The sample will be magnetically poled to prepare an imbalance in... -
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... -
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... -
Are La3Ni2NbO9 and La3Ni2TaO9 relaxor ferromagnets?
A relaxor ferroelectric exhibits a net polarisation only in an applied electric field due to the co-alignment of polar nanoregions. In La3Ni2SbO9 we found the magnetic... -
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... -
Neutron analysis of the structure of SrAl2O4 from 300 to 1273 K.
SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase... -
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... -
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... -

Novel functionality in condensed matter physics is one of fastest developing fields, aiming for possible future applications including quantum computing, electronic devices and... -
Neutron diffraction on filled ices with C_0 structure prepared between 3 and ...
The proposing team has a well established experience in the study on samples containingH_2 and D_2. Our recent neutron spectroscopic results on sII and sH H_2-filled clathrate... -
Exotic phase coexistence in magnetic and superconducting LaFe(As1-xPx)(O1-yFy)
The proposed 1111 system whose structures are largely underinvestigated exhibits properties with a strong potential for novel properties that complement our knowledge of the... -
Correlated local structure distortions in the family of high-temperature supe...
This proposal follows from a short previous test experiment (RB 920345) aimed at understanding the nature of local structure distortions in YBa2Cu3O6.9 and their possible role... -
Entangled superconductivity and magnetic and charge density waves in A1-xA'xF...
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...
