Degrees incorporating this pedagocial element :


Magnetism is commonly found in our everyday environment, mainly through the use of magnetic materials (motors and actuators, magnetic recording, MRI, etc.). It is also a highly active field of fundamental research, especially in Grenoble. The mesoscopic and macroscopic aspects are presented in detail, and the complex magnetic structures that are currently the focus of research are discussed. This course is based on the following plan:

  1. Introduction (link with S1, review of notations, M, B and H units)
  2. Magnetic behaviour
  • review (dia-, para-, ferro-), 
  • antiferromagnetic and ferrimagnetic ordering, 
  • frustrated ordering, 
  • multiferroics, 
  • magnetic semiconductors.

3.   Nanoscale ferromagnetism

  • Demagnetising field
  • Linear magnetism (definition of susceptibility)
  • Energies and equilibrium (including exchange coupling and energy interface)
  • Stoner-Wohlfarth, superparamagnetism
  • Beyond Stoner-Wohlfarth (domain walls)

4.  Characterisation methods and applications

  • Inductive measurements (magnetisation, susceptibility)
  • Force measurements (magnetic force microscopy)
  • Measurements of structures, spin orientations (interactions with neutrons or photons: diffraction, XMCD)
  • Magneto-optics (memory systems)
  • Soft/hard FM materials (transformers, electromagnets, (micro)motors, (micro)transducers, (micro)sensors)
  • Magnetostriction (motors, sensors)
  • Spintronics (magnetic memory, magnetic sensors, oscillators)

Recommended prerequisite

Solid-state Physics 1 course (microscopic magnetism)
