Understanding negative compressibility in KMn[Ag(CN)2]3
Negative linear compressibility (NLC) is the phenomenon whereby at least one of the linear dimensions of a material actually expand under hydrostatic pressure. It is only... -
Structural evolution in the solid solution Na2-x+yHxTi3O7 studied by neutron ...
Layered Na2Ti3O7 has shown promising electrochemical performance to be used as anode material in room temperature sodium ion batteries. We have synthesized several phases in the... -
Competing degenrate magnetic states in Ba1-xNaxFe2As2
Magnetic and superconducting ground states have been proposed to coexist in a relatively narrow compositional range in the so-called 122 pnictide superconductors. We recently... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we...
