Superconductivity up to 37 K in (A1-xSrx)Fe2As2 with A=K and Cs (2008)
Sasmal, K., Lv, B., Lorenz, B., Guloy, A., Chen, F., Xue, Y., ...
A new hight Tc Fe-based compound system, AFe2As2 with A = K, Cs, K/Sr and Cs/Sr has been found. Through electron-doping, Tc of the A = K and Cs compounds rises to ~37 K, and finally enter a...
Raman phonons in ReOFeAs (Re= Sm, La) (2008)
Hadjiev, V. G., Iliev, M. N., Sasmal, K., Chu, C. W.
We report the polarized Raman spectra of undoped ReOFeAs (Re = Sm, La) collected at room temperature from $ab$ surfaces of impurity free microcrystals. The spectra exhibit sharp phonon lines on very...
Lorenz, B., Sasmal, K., Chaudhury, R. P., Chen, X. H., Liu, R. H., Wu, T., ...
High temperature superconductors with a Tc above 40 K have been found to be strongly correlated electron systems and to have a layered structure. Guided by these rules, Kamihara et al. discovered a...
