Alex Gurevich,Satyabrata Patnaik,V. Braccini,Kee Hoon Kim,Charles H. Mielke,Xueyan Song,Lance D. Cooley,Sang Don Bu,D. M. Kim,J. H. Choi,L. J. Belenky,J. E. Giencke,M. K. Lee,Wei Tian,Xiaoqing Pan,Antonio Sergio Siri,Eric E. Hellstrom,Chang-Beom Eom,David C. Larbalestier +18 more
TL;DR: In this paper, the authors reported a significant enhancement of the upper critical field Hc2 of different MgB2 samples alloyed with nonmagnetic impurities, which can be explained by a theory of two-gap superconductivity in the dirty limit.

TL;DR: In this paper, the effect of alloying on the upper critical field was investigated for 12 C-alloyed films, in which disorder was introduced by growth, carbon doping or He-ion irradiation.
Journal ArticleDOI
Improved upper critical field in bulk-form magnesium diboride by mechanical alloying with carbon
Benjamin J. Senkowicz,J. E. Giencke,Satyabrata Patnaik,Chang-Beom Eom,Eric E. Hellstrom,David C. Larbalestier +5 more
TL;DR: In this paper, high-energy milling of magnesium diboride prereacted powder renders the material largely amorphous through extreme mechanical deformation and is suitable for mechanically alloying MgB2 with dopants including carbon.
