The phase behaviour and thermoelastic properties of SnMo2O8, derived from variable temperature and pressure synchrotron powder diffraction data, are reported. SnMo2O8 is a member of the AM2O8 family of negative thermal expansion (NTE) materials, but... Read More about Phase behaviour, thermal expansion and compressibility of SnMo 2 O 8.

Crystal field excitations and magnons: Their roles in oxyselenides Pr2O2M2OSe2 (M = Mn, Fe) (2017)

We present the results of neutron scattering experiments to study the crystal and magnetic structures of the Mott-insulating transition metal oxyselenides Pr2O2M2OSe2 (M = Mn, Fe). The structural role of the non-Kramers Pr3+ ion was investigated, and... Read More about Crystal field excitations and magnons: Their roles in oxyselenides Pr2O2M2OSe2 (M = Mn, Fe).
