Magnetic ordering in CaFe3O5 and CaFe5O7
This proposal is to explore the evolution of magnetic ordering in two members of the homologous series CaFe2O4(FeO)n with n = 1, & 3, and to correlation the behaviour of the... -
Is dynamic asymmetry the essential ingredient in the (universal?) 'strong-fra...
We want to elucidate whether the so-called ¿strong-fragile¿ transition reported for water mixtures is a universal phenomenon driven by confinement effects originated by the... -
Intra-block magnetic excitations in KFe0.8Ag1.2Te2
KFe0.8Ag1.2Te2 is made of 2x2 squares of Fe atoms, upon lowering temperature the system spontaneously undergoes a transition that breaks the fourfold rotational symmetry. A... -
Inelastic neutron scattering study on the Spin-Lattice interaction in the Spi...
AB2O4 is one of the most investigated systems due to the interaction between electron, spin, orbital, and lattice, which lead to the anormal physical properties:a) the orbital... -
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... -
Negative thermal expansion in the rutile phase of ZnF2
It has recently been discovered than the rutile phase of zinc fluoride shows negative thermal expansion along all three crystallographic axes. What is highly unusual about this...
