We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a... -
Proton/deuteron mobility in ammonium hexachlorometallates.
The piloting experiments RB820478, RB610497 and RB 10067 on VESUVIO on (NH4)2PdCl6 and (NH4)2TeCl6 have shown that: (i) at 300 K, the dynamics of NH4+ and PdCl6- and TeCl6- is... -
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... -
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... -
