Bulk superconductivity at an elevated temperature (T c ≊12 K) in a nickel containing alloy system Y-Ni-B-C
R. Nagarajan,R. Nagarajan,R. Nagarajan,Chandan Mazumdar,Chandan Mazumdar,Chandan Mazumdar,Z. Hossain,Z. Hossain,Z. Hossain,S. K. Dhar,S. K. Dhar,S. K. Dhar,K. V. Gopalakrishnan,K. V. Gopalakrishnan,K. V. Gopalakrishnan,L. C. Gupta,L. C. Gupta,L. C. Gupta,C. Godart,C. Godart,C. Godart,B. D. Padalia,B. D. Padalia,B. D. Padalia,R. Vijayaraghavan,R. Vijayaraghavan,R. Vijayaraghavan +26 more
TL;DR: In this article, the authors reported the discovery of bulk superconductivity at rather high (g10 K) values in samples having nominal compositions (i.e., they had nickel in large proportions) and showed that these materials are distinct superconductors.
Journal ArticleDOI
Superconductivity at 12 K in YNiB system
Chandan Mazumdar,R. Nagarajan,C. Godart,L. C. Gupta,Michel Latroche,S. K. Dhar,Claude Lévy-Clément,B. D. Padalia,R. Vijayaraghavan +8 more
TL;DR: In this article, a superconducting transition at 12 K was observed in the system YNi4B (nominal composition: YNi3B), and the possibility of a magnetic phase transition at this temperature was ruled out by specific heat measurements.
Journal ArticleDOI
Magnetic structure of EuFe 2 As 2 determined by single-crystal neutron diffraction
Yinguo Xiao,Yixi Su,M. Meven,Ranjan Mittal,Ranjan Mittal,C. M. N. Kumar,Tapan Chatterji,S. Price,Jörg Persson,Neeraj Kumar,S. K. Dhar,Arumugam Thamizhavel,Th. Brueckel +12 more
TL;DR: In this article, a single crystal neutron diffraction study was carried out to determine the magnetic structure of EuFe2As2 and investigate the coupling of two magnetic sublattices.
Journal ArticleDOI
Strong itinerant magnetism in ternary boride CeRh3B2
TL;DR: In this paper, a high-temperature itinerant ferromagnet CeRh3B2 was reported to order magnetically at 115K. The magnetic ordering seems to be intrinsic and presumably arises from the Rh d-band.
Journal ArticleDOI
Growth of epitaxial and polycrystalline thin films of the electron doped system La1−xCexMnO3 through pulsed laser deposition
TL;DR: In this paper, a broad metal insulator transition (MIT) is resolved into two peaks, suggesting the presence of a second (impurity) phase, which is identified as unreacted CeO2 by the intensity analysis of the x-ray diffraction (XRD) data.
