Magnetic characterization is the process of measuring and analyzing the magnetic properties of materials. This includes determining how materials respond to magnetic fields, which can reveal important information about their structure and composition. Common techniques used in magnetic characterization include vibrating sample magnetometry and superconducting quantum interference devices (SQUID). Understanding the magnetic properties of materials is crucial in various fields, such as materials science, electronics, and geophysics. These properties can influence the performance of devices like hard drives and magnetic sensors, making magnetic characterization essential for developing new technologies and improving existing ones.
