Inelastic neutron scattering study of exchange disorder in CaFe2O4 and CaFe1....
We would like to investigate polycrystalline CaFe2O4 which undergoes two magnetic transitions to a B phase below 190 K and to a A phase below 160 K. Both phases coexist in a... -
Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -
Molecular dynamics and melting in CH3NH3PbCl3:
The organic-inorganic perovskites (CH3NH3Pb(Br,Cl,I)3) have been identified as efficient photovoltaic materials. Theoretical calculations have suggested that the low energy... -
Proton dynamics in novel organic ferroelectric materials
The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in...
