概要
- 論文の詳細を見る
The upper critical field H_<υ2> is evaluated for weakly-coupled two-hand anisotropic superconductors. By modeling the actual hands and the gap distribution of MgB : by two Fermi surface spheroids with average parameters of the real material, we show that H_<υ2,ab>/H_<υ2,ab> increases with decreasing temperature inagreement with available data.
