Magnetic materials play a major role in the progress of industrial and scientific development. They are used in sensing, data storage, power generation, and medical devices among many others. Characterizing magnetic materials is a crucial step for understanding their physical properties and identifying new potential applications.

In this webinar, Jelena Trbovic and Yury Bugoslavsky (Cryogenic Ltd) will look into the basics of magnetism and present characterization methods that take advantage of lock-in amplifiers. You will learn how to distinguish between different types of magnetic materials using common magnetization characterization methods, such as those based on the vibrating sample magnetometer (VSM) and AC susceptibility. As lock-in amplifiers are key elements for these approaches, you will learn how they work and how to ensure that your measurements are performed correctly.
