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…
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…
Ferromagnetism and spin polarized charge carriers in InO thin films
Raghava P. Panguluri, P. Kharel, C. Sudakar +6
We present evidence for spin polarized charge carriers in InO films. Both InO and Cr doped InO films exhibit room temperature ferromagnetism after vacuum an…
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…
Ferromagnetism at 300 K in spin-coated anatasea and rutile Ti0.95Fe0.05O2 films
R. Suryanarayanan, V. M. Naik, P. Kharel +2
Thin films of Ti1-xFexO2 (x=0 and 0.05) have been prepared on sapphire substrates by spin-on technique starting from metal organic precursors. When heat treated in air at 550 and 7…
Ferromagnetism at 300 K in spin-coated films of Co doped anatase and rutile TiO2
R. Suryanarayanan, Vaman Naik, Parasuram Kharel +2
Thin films of Ti1-xCoxO2 (x=0 and 0.03) have been prepared on sapphire substrates by spin-on technique starting from metalorganic precursors. When heat treated in air at 550 and 70…
