In recent years there has been a growing interest in modifying the anion lattice of complex transition metal oxides, via topochemical manipulation, to tune the magnetic and...

New layered perovskite compounds LaBaFeMnO5 and LaBaFeMnO6 were recently synthesized. They may be useful for future oxygen storage applications. Fe-Mössbauer spectroscopy has...

Manganese oxides have attracted great interest in solid-state physics research owing to the diverse range of electronic ordering phenomena. Pb3Mn7O15 is a relatively...

Polar A2BSbO6 oxides with the Ni3TeO6 structure type (space group R3) are being investigated as possible ferroelectrics. Ni2ScSbO6 is reported to have incommensurate helical...

We propose to perform neutron diffraction experiments on single crystals, 3R-AgFeO2 and 2H-AgFeO2 on WISH. Recently, we have studied magnetic orderings and ferroelectricity of...

A previous CRISP measurement allows us to show for the first time using PNR a change in the response due to superconductivity in an Fe/Pb/Fe tri-layer sample. This type of...

Experiments (many at ISIS) using crystallographic methods, total scattering, inelastic neutron scattering and theory have provided a detailed picture of the origin of strong...

This proposal is a continuation access to a recent experiment conducted at OSIRIS (RB1510529) to study the quantum tunneling characteristics of ZIF-8, which is a cubic...

The proposal is dedicated to the first magnetic unconventional clathrate EuNi2P4. By resolving the low-temperature (below 15K) nuclear and magnetic strucutres we should be able...

Lead based oxides are wildly used in material science in order to obtain non-centrosymmetric structures that eventually lead to polar or piezoelectric distortion, which coupled...

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...

Both 1D physics (dimensional frustration) and geometric frustration offer ways of achieving unusual quantum ground states that defy the usual tendency for systems to order at...

We had been given 1 day of beam time on WISH, RB1710144, to investigate the magnetic structure of T2V2O7 (T=Mn, Ni, Co) We performed power neutron diffraction measurements on...

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...

Cerium and ytterbium are two members of the lanthanide (rare earth) series of elements that haverevealed in their intermetallic compounds new physics and many interesting...

The crystal structure of PrFe2Al8 consists of a network of Al which forms quasi cage-like structure where the Pr and the Fe form chains of atoms along the c-axis. We propose...

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...

Materials exhibiting giant magnetocaloric effect (i.e. the large temperature change under a magnetic field variation) are the most promising type for magnetic refrigeration....

Yttrium iron garnet Fe3Y5O12 (YIG) is the material of choice for spin Hall related effects, magnonics, inter alia and has been used in microwave applications for many years....

Our recent study of CaFe3O5 revealed a remarkable discovery of electronic phase separation, similar to examples widely reported in manganite perovskites. Electronic phase...
