Lecture

Magnetic Anisotropy: Observations in Iron, Nickel, and Cobalt

Description

This lecture explores the concept of magnetic anisotropy by analyzing magnetization curves for iron, nickel, and cobalt along different crystallographic directions, highlighting the differences in behavior and energy levels. The presentation delves into the microscopic reasons behind these observations, emphasizing the impact of spin-orbit coupling on the orbital functions during magnetic rotation. Through a series of comparisons and visual aids, the instructor provides a comprehensive introduction to magnetic materials in modern technologies, shedding light on the crucial role of magnetic anisotropy in material properties and applications.
