Magnetism and Magnetic Materials

• Describe why materials have magnetic moments
• Describe why and how magnetic moments in materials interact
• Calculate the magnetic response of a magnetic material to an external magnetic field
• Describe and visualize the different types of magnetically ordered structures (ferro-, antiferro-, and ferrimagnets)
• Calculate the magnetic phase transition temperature in the mean field model
• Derive an expression for magnetic excitations (spin waves)
• Explain formation of magnetic domains and single-domain properties
• Explain the particular magnetic properties of nanoparticles
• Describe the principles in a series of magnetic measurement techniques: magnetometry, magnetic imaging, nuclear magnetic resonance (NMR), neutron scattering

Magnetic moments in solids, magnetic interaction, magnetic ordering, ferromagnetism, ferrimagnetism and antiferromagnetism, magnetic model systems, magnetic domains, spin waves, magnetic particles, magnetic materials, NMR, magnetization measurements, neutron scattering, magnetic imaging
