In the case of thin films (film thickness small compared to coherence length) the angular dependence of the critical magnetic field H_c shows good agreement with an interpolation formula derived by Tinkham. In thick films exhibiting the surface superconductivity in a magnetic field parallel to the film the experimantal results deviate from the theory. These results are discussed on the basis of the Gizburg-Landau theory.}, pages = {81--92}, title = {マイクロ波超音波による超伝導薄膜の研究 : 臨界磁場H_cの角度依存性}, volume = {19}, year = {1984}, yomi = {アカオ, フミオ and クボ, ヨシオ} }
