Journal ArticleDOI
Improved superconducting properties in nanocrystalline bulk MgB2
TL;DR: In this paper, high density nanocrystalline MgB2 bulk superconductors with distinctly improved pinning were prepared by mechanical alloying of Mg and B powders at ambient temperatures followed by hot pressing.
Journal ArticleDOI
Evolution of magnetic domain structures and coercivity in high-performance SmCo 2:17-type permanent magnets
Oliver Gutfleisch,K.-H. Müller,K. Khlopkov,M. Wolf,Aru Yan,Rudolf Schäfer,Thomas Gemming,Ludwig Schultz +7 more
TL;DR: The magnetic domain structure of SmCo 2:17-type magnets has been found to be very sensitive to details of the processing procedure as mentioned in this paper, which leads to a much coarser domain structure (domain width ∼10μm) and a small coercivity (
Journal ArticleDOI
Improved superconducting properties in nanocrystalline bulk MgB_2
TL;DR: In this article, high-density nanocrystalline MgB_2 bulk superconductors with improved pinning were obtained by mechanical alloying of Mg and B powders and hot compaction at ambient temperatures.
Journal ArticleDOI
Large magnetocaloric effect in melt-spun LaFe13−xSix
TL;DR: In this article, a very large value of magnetic entropy change ∣ΔS∣=31J∕kgK was obtained at 201K under 5T in LaFe11.8Si1.2 melt-spun ribbons subjected to a very short-time annealing (2h∕1050°C).
Journal ArticleDOI
Superconducting bulk magnets: Very high trapped fields and cracking
TL;DR: In this article, the authors reported improved trapped fields for bulk melt-textured YBa2Cu3O7−δ (YBCO) material in the temperature range between 20 and 50 K.
