Abstract
We measured the upper critical field mu(o)H(c2) for a modified Nb3Al s ample above 10K and evaluated the values using a different criterion. The values from the I-c measurement, converting from the ac susceptibi lity and direct judging from the transition point on the magnetization curve, were close and larger than that extrapolated from the magnetiz ation based on the theory of Kramer and the critical state model.
