Magnetism - KAMA7M09

Goal(s)

The "Physics-Fundamentals" course is a classic introduction to solid state physics, with in a first part the nature of crystalline bonds and their role in physical properties, the quantization of phonon network vibrations and the consequences on the thermal properties. The second part of the course goes on the electronic properties of solids based on a description of the electron conduction by the free electron gas model of Drude, then an improvement of the model by a quantum approach. The next chapter will be devoted to band theory. The last two chapters will focus on the electronic properties of metals and semiconductors. The third part of the course gives an engineer the basic knowledge for a good understanding of magnetic materials. The course starts with a study of the physics of magnetism and details the four
energies that govern the magnetic behavior of materials (exchange energy, Zeeman energy, demagnetizing energy and magnetocrystalline energy).
