M2 Nanomagnetism and Spintronics 2013-2014 #

For the 2013-2014 edition of this lecture course of the Masters 2 Nanosciences Saclay programme, I will be giving three lectures on the following topics:

Lecture 4: Micromagnetic theory – Statics

  • Magnetic Hamiltonian
  • Domain structures
  • Domain walls and vortices
  • Problem set 1

Lecture 5: Magnetisation dynamics

  • Magnetisation precession, torques
  • Linear excitations: Spin waves
  • Nonlinear excitations: Domain walls, vortices
  • Problem set 2

Lecture 6: Topology and chirality in nanomagnetism

  • Domain walls (solitons, antisolitons)
  • Vortices and antivortices
  • Spin spirals
  • Skyrmions
  • Highlights from current research
  • Problem set 3
