Anomalous heat capacity and X-ray photoelectron spectroscopy of Superconducting FeSe1/2Te1/2
V. P. S. Awana, Govind, Anand Pal +5
The bulk polycrystalline sample FeSe1/2Te1/2 is synthesized by solid state reaction route in an evacuated sealed quartz tube at 750 oC. The presence of superconductivity is confirm…
Intriguing complex magnetism of Co in RECoAsO (RE=La, Nd and Sm)
Anand Pal, M. Tropeano, Mushahid Hussain +2
We synthesized bulk polycrystalline samples of RECoAsO (RE=La, Nd and Sm) by solid state reaction route in an evacuated sealed quartz tube. All these compounds are crystallized in…
Appearance and disappearance of superconductivity with Fe site Co substitution in SmFe1-xCoxAsO (x = 0.0 to 1.0)
V. P. S. Awana, Anand Pal, Mushahid Hussain +1
We report synthesis, structural details and magnetization of SmFe1-xCoxAsO with x ranging from 0.0 to 1.0 at close interval of 0.10. It is found that Co substitutes fully at Fe sit…
Induction of superconductivity by sulphur doping in FeTe system and post effect of low temperature oxygen annealing
V. P. S. Awana, Anand Pal, Arpita Vajpayee +2
Here, we report the synthesis and characterization of sulphur-substituted iron telluride i.e. FeTe1-xSx; (x = 0-30 %) system and study the impact of low temperature oxygen (O2) ann…
Intergrain effects in the AC susceptibility of polycrystalline LaFeAsO_{0.94}F_{0.06}: comparison with cuprate superconductors
G. Bonsignore, A. Agliolo Gallitto M. Li Vigni, J. L. Luo +3
The AC susceptibility at zero DC magnetic field of a polycrystalline sample of LaFeAsO_{0.94}F_{0.06} (T_c = 24 K) has been investigated as a function of the temperature, the ampli…
Valence band and core-level analysis of highly luminescent ZnO nanocrystals for designing ultrafast optical sensors
Amish G. Joshi, Sonal Sahai, Namita Gandhi +2
Highly luminescent ZnO:Na nanocrystals of size ~2 nm were synthesized using a improved sol-lyophilization process. The surface analysis such as survey scan, core-level and valence…
Current-driven orbital order-disorder transition in LaMnO3
Parthasarathi Mondal, Dipten Bhattacharya, P. Mandal
We report significant influence of electric current on the orbital order-disorder transition in LaMnO3. The transition temperature T_OO, thermal hysteresis in the resistivity (rho)…
Network of Earthquakes and Recurrences Therein
T. R. Krishna Mohan, P. G. Revathi
We quantify the correlation between earthquakes and use the same to distinguish between relevant causally connected earthquakes. Our correlation metric is a variation on the one in…
