Low temperature and high pressure Raman and x-ray studies of pyrochlore TbTiO : phonon anomalies and possible phase transition
Surajit Saha, D. V. S Muthu, Surjeet Singh +8
We have carried out temperature and pressure-dependent Raman and x-ray measurements on single crystals of TbTiO. We attribute the observed anomalous temperature depende…
Colossal electroresistance and colossal magnetoresistive step in paramagnetic insulating phase of single crystalline bilayered manganite(LaPr)SrMnO
Y. Yamato, M. Matsukawa, R. Suryanarayanan +5
We report a significant decrease in the low-temperature resistance induced by the application of an electric current on the -plane in the paramagnetic insulating (PMI) state of…
Temperature dependent Raman and x-ray studies of spin-ice pyrochlore and non-magnetic pyrochlore
Surajit Saha, Surjeet Singh, B. Dkhil +5
We present here temperature-dependent Raman, x-ray diffraction and specific heat studies between room temperature and 12 K on single crystals of spin-ice pyrochlore compound $Dy_2T…
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…
Manifestation of geometric frustration on magnetic and thermodynamic properties of pyrochlores (X=Ti, Zr)
Surjeet Singh, Surajit Saha, S. K. Dhar +3
We present here magnetization, specific heat and Raman studies on single-crystalline specimens of the first pyrochlore member of the rare-earth titanate series. Its a…
Dynamical spin chirality and spin anisotropy in gapped S=1/2 quantum systems
J. E. Lorenzo, C. Boullier, L. P. Regnault +2
We have studied the spin anisotropy in spin-singlet ground state compounds and the magnetic chirality, as measured by inelastic polarized neutron scattering techniques, in the chai…
