Vibrational properties of hydrogen in niobium oxide
Niobium oxide based compounds have superior catalytic properties. Research to get an inside into the physical properties of hydrogen is extremely difficult as hydrogen in Nb2O5... -
Local Structure in (K,Na)NbO3 Piezoelectric Ceramics
KxNa1-xNbO3 (KNN)-based solid solutions are promising lead-free piezoelectrics for ceramic actuators. In this system, the long-range order of octahedral rotations and... -
Magnetic Excitations of Isolated and Pairs of Co Ions and in MgO
The magnetic excitations will be studied in a powdered sample of 3% CoO in 97% MgO in order to to study the excitations of isolated Co ions and of isolated pairs of Co ions.... -
YMnO3-x : Mn(I) in a mixed metal oxide ?
Topotactic reduction of YMnO3 with CaH2 yields three new reduced phases. Two of these phases appear to have compositions close to YMnO2.5 but with very different anion vacancy...
