磁滞回线表征了从物理学、化学到经济学和社会学等领域的各种行为。特别是，它们代表了铁磁材料如铁磁和铁电的主要特性，近年来，由于它们的多功能特性而引起了人们的极大兴趣。虽然测量这样的回路在实验上可能并不复杂，但是由于对所测量的滞后的不同贡献，提取回路的特征参数的固有值可能被证明是困难的。在本文中，提出了一种简单的技术来分析磁滞回线，并提取单独的铁磁或铁电材料的贡献。这种方法包括区分所测量的回路，对不同的贡献进行去卷积，并选择性地仅对属于铁性响应的信号进行积分。的方法的局限性的讨论。不同的测量铁磁和铁电的磁滞回线也被用来验证该技术。实验数据与重建数据的比较表明了该方法的准确性和可靠性。此外，应用这种方法使我们能够突出的Bi2FeCrO6室温多铁性薄膜，以前没有观察到的属性。由AIP出版社出版。
Hysteresis loops characterize a wide variety of behaviors in fields ranging from physics and chemistry to economics and sociology. In particular, they represent the main characteristic of ferroic materials such as ferromagnetic and ferroelectric, which, in recent years, have attracted much interest due to their multifunctional properties. Although measuring such loops may not be experimentally complicated, extracting the intrinsic values of the characteristic parameters of the loop may prove difficult due to the different contributions to the measured hysteresis. In this paper, a simple technique is proposed to analyze hysteresis loops and to extract solely the contribution of the ferromagnetic or ferroelectric material. Such method consists in differentiating the measured loop, deconvoluting the different contributions and selectively integrating only the signals belonging to the ferroic response. A discussion of the limitations of the method is presented. Different measured ferromagnetic and ferroelectric hysteresis loops were also used to validate the technique. Comparison between experimental and reconstructed data demonstrated the precision and reliability of the technique. Moreover, application of such method allowed us to highlight properties of a Bi2FeCrO6 room temperature multiferroic thin film that were not previously observed. Published by AIP Publishing.
