Magnetic Characterization Techniques for Advanced Functional Materials

Abstract

Magnetic characterization techniques play a fundamental role in understanding the physical properties of advanced functional materials used in modern technological applications. These materials, including magnetic nanomaterials, spintronic devices, and multifunctional composites, require precise evaluation of their magnetic behavior to optimize performance. Techniques such as vibrating sample magnetometry, superconducting quantum interference device magnetometry, magnetic force microscopy, and ferromagnetic resonance provide detailed insights into magnetic parameters including magnetization, coercivity, anisotropy, and spin dynamics. These characterization methods enable researchers to study magnetic domain structures, magnetic phase transitions, and nanoscale magnetic interactions. This article reviews the key magnetic characterization techniques used in advanced functional materials research, emphasizing their working principles, advantages, and applications in materials science and nanotechnology. The paper also highlights emerging characterization approaches that support the development of next-generation magnetic materials for electronics, energy systems, and biomedical technologie
