Nanomagnetism and Spin Dynamics
The lecture will be given by Professor Ternes.
- 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
Basic knowledge on classical electrodynamic, quantum mechanic, and solid state physics are helpful but not required.
The lecture intends to give an introduction to the field of nanomagnetism and spin dynamics with some focus on recent experimental phenomena.
