Nanomagnetism and Spin Dynamics

 

Lecture details

The lecture will be given by Professor Ternes.

Description:

  • Brief repetition of the basic physical properties of classical magnetism
  • Emerging properties due to the reduction of dimensionality
  • Ferromagnetism and Domain walls
  • Giant magneto-resistance and tunnel magneto-resistance
  • Superparamagnetism and blocking temperature
  • Magnetic anisotropy and spin-orbit-coupling
  • Coupling of spins: dipolar, direct exchange, orbital overlap, and super-exchange
  • Ising, Heisenberg, and Dzyaloshinskii-Moriya interactions
  • Excitations in coupled spins: Magnons and Spinons
  • Emerging effects by coupling to bath systems: Kondo effect and intra-gap states in superconductors
  • Dynamics of quantum spins, Bloch sphere and electron paramagnetic resonance
  • Magnetometry and magnetic imaging techniques at the nanoscale

Prerequisites:

Basic knowledge on classical electrodynamic, quantum mechanic, and solid state physics are helpful but not required.

Learning goal:

The lecture intends to give an introduction to the field of nanomagnetism and spin dynamics with some focus on recent experimental phenomena.
