| Popis: | We investigated the effect of alloying on the upper critical field Hc2 for 12 MgB2 films, in which disorder was introduced by growth, carbon doping or He-ion irradiation, finding a significant Hc2 enhancement in C-alloyed films, and an anomalous upward curvature of Hc2sTd. Record high values of Hc2 's4.2d |
