Phonon and crystal field excitations in geometrically frustrated rare earth titanates
T. T. A. Lummen, I. P. Handayani, M. C. Donker +5
The phonon and crystal field excitations in several rare earth titanate pyrochlores are investigated. Magnetic measurements on single crystals of Gd2Ti2O7, Tb2Ti2O7, Dy2Ti2O7 and H…
A Raman study of the Charge-Density-Wave State in AMoO (A = K,Rb)
D. M. Sagar, D. Fausti, S. Yue +3
We report a comparative Raman spectroscopic study of the quasi-one-dimensional charge-density-wave systems \ab (A = K, Rb). The temperature and polarization dependent experiments r…
Symmetry disquisition on the TiOX phase diagram
Daniele Fausti, Tom T. A. Lummen, Cosmina Angelescu +11
The sequence of phase transitions and the symmetry of in particular the low temperature incommensurate and spin-Peierls phases of the quasi one-dimensional inorganic spin-Peierls s…
Coherent amplitudon generation in K_0.3MoO_3 through ultrafast inter-band quasi particle decay
D. M. Sagar, A. A. Tsvetkov, D. Fausti +2
The charge density wave system K_0.3MoO_3 has been studied using variable energy pump-probe spectroscopy, ellipsometry, and inelastic light scattering. The observed transient refle…
Raman scattering from phonons and magnons in RFe3)BO3)4
Daniele Fausti, Agung Nugroho, Paul H. M. van Loosdrecht +3
Inelastic light scattering spectra of several members of the RFe3(BO3)4 family reveal a cascade of phase transitions as a function of temperature, starting with a structural, weakl…
