研究了在平行于薄膜表面的磁场中，薄膜(d<；λ，其中为薄膜厚度，λ为伦敦穿透深度)中涡旋晶格的结构。结果表明，稳定位形具有离散涡行的形式，其数目随外加磁场的增加而离散变化。计算了n=1，2时涡列的入口场Hc1(N)(D)。结果表明，涡系综中的结构相变是二级相变。提出了一种计算涡旋晶格参数的简单方法(与蒙特卡罗方法相比)。
The structure of a vortex lattice in thin (d<λ, wheredis the film thickness and λ is the London penetration depth) superconducting films is investigated in a magnetic field parallel to the film surface. It is shown that the stable configuration has the form of discrete vortex rows whose number changes discretely with an increase in the applied magnetic field. The entry fieldsHc1(N)(d) for vortex rows are calculated forN=1, 2. It is shown that the structural transition in the vortex ensemble is a second-order phase transition. A simpler method (as compared to the Monte Carlo technique) is proposed for calculating the vortex lattice parameters.
