課程概述 |
In this course we will cover the modern perspective of magnetism and magnetic materials.
The lecture will start from the basics of electromagnetism and quantum mechanics, then go deeper into the concepts of quantum spin, spin-orbit interaction, and exchange interaction…etc.
After understanding these basic principles, we will discuss the origins of various types of magnetic properties in different materials as well as the characterization techniques for obtaining these properties.
For the last part, we will discuss the modern approach of combining electronics and magnetism into one big spintronics picture. We will go over some remarkable discoveries such as Giant magnetoresistance (GMR) and spin transfer torque (STT), which revolutionized the contemporary magnetic-memory development. |
