Evidence for Defect-induced Superconductivity up to 49 K in (Ca1-xRx)Fe2As2
L. Z. Deng, B. Lv, K. Zhao +4
To explore the origin of the unusual non-bulk superconductivity with a Tc up to 49 K reported in the rare-earth-doped CaFe2As2 , the chemical composition, magnetization, specific h…
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…
Superconductivity in the Mn5Si3-type Zr5Sb3 system
B. Lv, X. Y. Zhu, B. Lorenz +5
We report the discovery of superconductivity at 2.3 K in Zr5Sb3, the first superconducting member in the large compound family of the Mn5Si3-structure type. Transport, magnetic, an…
The simultaneous occurrence of superparamagnetism and superconductivity in nominal single crystalline (Ca1-xPrx)Fe2As2 with 0 <= x <= 0.13
B. Lv, F. Y. Wei, L. Z. Deng +2
The observation of non-bulk superconductivity with an unexpectedly high onset transition temperature Tc up to ~ 49 K in non-superconducting single crystalline CaFe2As2 upon rare-ea…
Absence of zero-energy surface bound states in CuxBi2Se3 via a study of Andreev reflection spectroscopy
Haibing Peng, Debtanu De, Bing Lv +2
CuxBi2Se3 has been proposed as a potential topological superconductor characterized by an odd-parity full bulk superconducting gap and zero-energy surface Andreev bound states (Maj…
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…
Lower Critical Field, Anisotropy, and Two-Gap Features of LiFeAs
K. Sasmal, B. Lv, Z. Tang +4
The magnetic properties of LiFeAs, as single crystalline and polycrystalline samples, were investigated. The lower critical field deduced from the vortex penetration of two single…
Evidence for multiple gaps in specific heat of LiFeAs crystals
F. Wei, F. Chen, K. Sasmal +5
The zero-field specific heat of LiFeAs was measured on several single crystals selected from a bulk sample. A sharp Delta Cp/Tc anomaly of approximately 20 mJ/(mole x K^2) was obse…
