High field superconductivity in thin films
Thin films provide an ideal means for studying the role of spin paramagnetism in the theory of superconductivity. A review is given of the present state of theoretical and experimental work. It includes a study of the excitation spectrum of thin films in a parallel magnetic field and the experimental evidencp of Zeeman splitting of superconducting quasiparticlcs. The role of spinorbit interaction is discussed in detail. The application of spin selective tunnelling is shown. Furthermore, a study is included of the order of phase transition between the normal state and the paramagnetically limited superconducting state. A detailed discussion is given of the generalized Ginzburg-Landau equation including numerical evaluations. The applicability of Tinkham's formula STAPhys. Rev.; 129: 2417 (1963)! is discussed, which is relevant for the determination of critical fields of arbitrary orientations to the film. Finally, an account is given of the work which deals with the influence of spin paramagnetism on superconducting fluctuations. Recent experimental and theoretical work is described and discussed.
