We analyzed the role of the inclusion of anti-dots on the vortex state and some calorimetric properties of a mesoscopic superconducting square immersed in an external applied magnetic field. We calculated the magnetization, entropy, Gibbs free energy, density of Cooper pairs and specific heat for this system in a zero field cooling process, solving the time-dependent Ginzburg–Landau equations. We found that the critical temperature is non-dependent on the number of anti-dots and dependent slightly on the size of the defects. Oscillations in the entropy and specific heat are found due the temperature dependence of the superconducting characteristics length.

超导各向异性正方形的量热特性：ZFC 过程

我们分析了包含反点对涡流状态的作用以及浸入外部施加磁场中的介观超导正方形的一些量热特性。我们计算了该系统在零场冷却过程中的磁化强度、熵、吉布斯自由能、库珀对密度和比热，求解了与时间相关的 Ginzburg-Landau 方程。我们发现临界温度不依赖于反点的数量，并且略微依赖于缺陷的大小。由于超导特性长度的温度依赖性，发现了熵和比热的振荡。
