Description
This lecture covers the magnetoelastic effects in magnetic materials, focusing on the magnetostriction coefficient and its relation to the change in shape or dimensions during magnetization. It discusses the basics of magnetostriction, stress fields, elastic properties, and the impact of magnetic and elastic properties under stress. The presentation also delves into the invar effect, anisotropic magnetostriction, and how to measure strain in ferromagnetic materials. The lecture explores the field dependence of magnetostriction, including anisotropic effects, strain measurement directions, and the concept of magnetostiction. It concludes with a discussion on multi-domain variations in samples.
