Tracing the Magnetization Curves: a Review on Their Importance, Strategy, and Outcomes.

This article gives a review on some important experimental studies on the magnetization curves using different theoretical models. Applications of the law of approach to saturation magnetization and Langevin function to various kinds of magnetic materials belonging to different groups such as ferromagnetic, ferrimagnetic, antiferromagnetic, superparamagnetic materials at various experimental conditions, applied field ranges, and their dependencies on the applied field are collectively reviewed. Extraction of important magnetic parameters by fitting magnetization data with suitable models and their variation with composition, morphologies, size etc. along with the strategies adopted are also discussed. The purpose and outcomes of such studies along with future scope are also highlighted in this review. [ABSTRACT FROM AUTHOR]
