Why is the superconducting Tc so high in rare-earth-doped CaFe2As2?
F. Y. Wei, B. Lv, L. Z. Deng +3
In rare-earth doped single crystalline CaFe2As2, the mysterious small volume fraction which superconducts up to 49 K, much higher than the bulk Tc ~ 30s K, has prompted a long sear…
The Unusual Superconducting State at 49 K in Electron-Doped CaFe2As2 at Ambient
B. Lv, L. Z. Deng, M. Gooch +6
We report the detection of unusual superconductivity up to 49 K in single crystalline CaFe2As2 via electron-doping by partial replacement of Ca by rare-earth. The superconducting t…
Short-Range B-site Ordering in Inverse Spinel Ferrite NiFe2O4
V. G. Ivanov, M. V. Abrashev, M. N. Iliev +3
The Raman spectra of single crystals of NiFe2O4 were studied in various scattering configurations in close comparison with the corresponding spectra of Ni0.7Zn0.3Fe2O4 and Fe3O4. T…
Growth, magnetic properties and Raman scattering of La2NiMnO6 single crystals
M. N. Iliev, M. M. Gospodinov, M. P. Singh +4
Millimeter size single crystals of double perovskite La2NiMnO6 (LNMO) were grown by the High Temperature Solution Growth Method. The magnetic measurements and polarized Raman spect…
Characterizations of strain and defect free GaN nanorods on Si(111) substrates
H. W. Seo, Q. Y. Chen, M. N. Iliev +4
GaN-nanorods grown on Si(111) substrates are found strain- and defect-free as characterized by micro Raman spectroscopy, secondary electron (SE) and cathode-luminescence (CL) imagi…
Nonstoichiometry, Defects and Transport Properties in MgB2
Y. Y. Xue, R. L. Meng, B. Lorenz +3
The local composition Mg:B of MgB2 powder was systematically changed through annealing. Correlations were observed between the Mg loss and the lattice parameters a/c and the micros…
