Soft Modes in the Ferroelectric Semiconductor SbSI
Antimony sulfo-iodide (SbSI) exhibits strongly-coupled photoconductive, semiconducting, and ferroelectric properties. Until the discovery of the lead-oxide ferroelectric relaxor... -
Spin excitations in La2O2Fe2OSe2 ¿ A Mott insulator candidate
We propose to map out the spin excitations in La2O2FeOSe2 using the MARI chopper spectrometer on a powder sample. Although the structure of La2O2FeOSe2 has some similarities to... -
An Investigation on the Effects of B-site disorder on the well-isolated non-K...
Although stuffing in the quantum spin ice (QSI) Yb2Ti2O7 has been shown to play a vital role inthe selection of a ground state, the only study to address such disorder was... -

Magnetostriction in (Bi, La)-orthoferrites
We have recently observed unusual magnetostrictive behaviour in Bi0.5La0.5FeO3 (BLFO), a phenomenon which is not present in either solid solution end member. This proposal seeks... -
Density-driven structural transformations in magnesium silicate glass
The density-driven structural transformations in the magnesium silicate glass MgSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of... -
Molecular and framework dynamics in CH3NH3PbCl3
We propose to use MARI to measure the molecular and framework dynamics in CH3NH3PbCl3 which has become of interest in the context of efficient photovoltaics. CH3NH3PbCl3 is... -
