Effect of Anelasticity on Creep Behaviour
Nuclear power generation plants undergo start-up/shut-down load-temperature cycles during service operation. Components operating at temperatures in the creep regime can exhibit... -
Magnetic excitations in mesoporous hematite
We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One... -
Spin gap opening associated with an extraordinary magnetovolume effect in som...
We have discovered an unusual magnetovolume effect in the 6H-perovskite oxides Ba3BiIr2O9 and Ba3BiRu2O9. These compounds contain isolated face-sharing bi-octahedral dimers... -
Phonon Dispersion in the Organic Ferroelectric Croconic Acid
Organic ferroelectrics are important materials because of their technological applications in low-cost non-volatile memory elements. Single-crystal croconic acid (C5O5H2) is the... -
Incommensurate magnetic fluctuation in KFe2As2 at high energy
We clearly observed incommensurate (IC) magnetic excitation in KFe2As2 above Tc with Ei=80 mev on ARCS at ORNL. Though we got beam time at LET, we wish to see how the IC changes... -
Q dependence of the low energy magnetic fluctuations in Intermediate Valence ...
A strong Q-dependence of the magnetic response at characteristic energy of EK~kBTK (TK is a Kondo temperature) has been observed in recent inelastic neutron scattering studies... -
Relaxation dynamics of a Dy-based single molecule magnet
Single-molecule magnets (SMM) exhibiting slow magnetic relaxation have attracted increasing interest, both from a fundamental point of view, and for the potential practical... -
Is there an incommensurate magnetic resonance in La2-xSrxCuO4?
Most optimally-doped high- Tc cuprate superconductors show a magnetic excitation (known as the 'resonance') at q=(pi,pi ) whose intensity increases sharply below Tc. This...
