High critical fields in MgB2 thin films with various resistivity values

V. Ferrando, C. Tarantini, P. Manfrinetti +4

In this paper, we analyze the upper critical field of four MgB2 thin films, with different resistivity (between 5 to 50 mWcm) and critical temperature (between 29.5 to 38.8 K), mea…
