Synthesis and transport properties of ternary type-I Si clathrate K8Al7Si39
Shiva Kumar Singh, Takashi Mochiku, Soshi Ibuka +4
A ternary type-I Si clathrate, K8AlxSi46-x, which is a candidate functional material composed of abundant non-toxic elements, was synthesized and its transport properties were inve…
Appreciable magnetic moment and energy density in single step normal route synthesized MnBi
Nithya R. Christopher, Nidhi Singh, Shiva Kumar Singh +4
We study the structural and magnetic properties of the MnBi inter-metallic compound. The LTP (Low Temperature Phase) MnBi compound is successfully synthesized in single step by vac…
Impact of sintering temperature on room temperature magneto-resistive and magneto-caloric properties of Pr2/3Sr1/3MnO3
Ramesh Chandra Bhatt, Shiva Kumar Singh, P. C. Srivastava +2
Magneto-resistive and magneto-caloric properties of polycrystalline Pr2/3Sr1/3MnO3 have been studied as a function of sintering temperature (Ts) between 1260-1450°C. Reitveld refin…
Superconductivity at 5K in NdO0.5F0.5BiS2
Rajveer Jha, Anuj Kumar, Shiva Kumar Singh +1
We report appearance of superconductivity at 5K in NdO0.5F0.5BiS2 and supplement the discovery [1] of the same in layered sulfide based ZrCuSiAs type compounds. The bulk polycrysta…
Appearance of superconductivity in new BiS2 based layered LaO0.5F0.5BiS2
V. P. S. Awana, Anuj Kumar, Rajveer Jha +5
We report here synthesis, structural, DC magnetization, and transport studies of new BiS2 based layered LaO0.5F0.5BiS2 superconductor [1]. The sample was synthesized by conventiona…
Bulk Superconductivity in Bismuth-oxy-sulfide Bi4O4S3
Shiva Kumar Singh, Anuj Kumar, Bhasker Gahtori +4
Very recent report [1] on observation of superconductivity in Bi4O4S3 could potentially reignite the search for superconductivity in a broad range of layered sulphides. We report h…
