Barkhausen effect is a paradigmatic case of crackling noise and it offers insights on the complex microscopic magnetization process associated to the jerky motion of magnetic domain walls in ferromagnetic materials. The study of Barkhausen noise in magnetic films shows that the domain wall dynamics strongly depends on the structural characteristics of the material and film thickness. In fact, this phenomenon presents a dimensional transition that takes place for the thickness in the range from 100 to $50\mathrm{nm}$ in both cases: amorphous and polycrystalline films. Here we explore the entropy in the dynamics of magnetic domain walls using an entropy quantifier $\mathbf{S}$ based on the recurrence analysis. From the Barkhausen noise time series recorded in amorphous and polycrystalline films with distinct thicknesses, we address the entropy far from and at the dimensional crossover in the domain wall dynamics. Our findings reveal $\mathbf{S}$ presents a maximum at the dimensional transition; the distribution of $\mathbf{S}$ follows a Gaussian distribution for three-dimensional films far from the border of the dimensional crossover; the $\mathbf{S}$ distribution at the imminence of the dimensional crossover is not Gaussian, but strongly asymmetric, and despite the results are influenced by the film thickness, they seem to be insensitive to the structural characteristics of the materials.

巴克豪森效应是开裂噪声的典型案例，它为与铁磁材料中磁畴壁的急速运动相关的复杂的微观磁化过程提供了见解。对磁性薄膜中巴克豪森噪声的研究表明，畴壁动力学在很大程度上取决于材料的结构特征和薄膜厚度。实际上，这种现象会导致尺寸变化，厚度从100到100毫米不等。$50\mathrm{纳米}$在两种情况下：非晶膜和多晶膜。在这里，我们使用熵量词探索磁畴壁动力学中的熵$\mathbf{小号}$基于递归分析。根据记录在具有不同厚度的非晶和多晶薄膜中的巴克豪森噪声时间序列，我们解决了畴壁动力学中远离维数交界处和维数交界处的熵。我们的发现表明$\mathbf{小号}$在尺寸过渡处呈现最大值；的分布$\mathbf{小号}$遵循三维电影的高斯分布，远离三维分界线的边界；的$\mathbf{小号}$ 尺寸交越处的分布不是高斯分布，而是高度不对称，尽管结果受膜厚的影响，但它们似乎对材料的结构特性不敏感。
