Content, Learning Outcome and Preconditions


1) Magnetoelectronics - positive magnetoresistance - negative magnetoresistance - anisotropic magnetoresistance - AMR (spin-orbit coupling and magnetic resistance) - Colossal magnetoresistance - CMR (manganates, Goodenough-Kanamori-Anderson rules, super and double exchange) - giant magnetoresistance - GMR (Oscillating exchange coupling, exchange anisotropy, artificial antiferromagnets, Intrinsic and extrinsic GMR) - Spin Valves - tunnel magnetoresistance - TMR (elastic tunneling through 1D barriers, conductor/ insulator /conductor, conductor/ insulator /superconductor contacts, ferromagnet / insulator / superconductor contacts, quasiparticles density of states in superconductors, density and spin polarization in ferromagnet ferromagnet / insulator / ferromagnet contacts and Julliere model, band structure effects, spin-filter) - Unusual magnetoresistance - EMR  2) spintronics - spin injection into semiconductors - spin-LEDs and spin-transistors 3) applications - XMR sensors - magnetoresistive read heads, hard drives - Magnetic Random Access Memory - MRAM 

Learning Outcome

After successful completion of this module, the student is able

  1. to understand explain and compare magneto-Resisitive effects (anistrope magnetoresistance, colossal magnetoresistance, giant magnetoresistance, tunneling magnetoresistance)
  2. to describe the magnetization and magnetoresistance curves of ferromagnetic layers and multilayers as a function of the magnetic field
  3. to name elemental ferromagnets, some technically relevant soft and hard magnetic materials, as well as typical materials in magneto-electronic layer structures with the appropriate material parameters (Curie temperature, remanence, coercive field)
  4. to calculate magnetoresistance effects with Boltzmann transport theory and tunneling theory in the one-dimensional limit
  5. to describe ferromagnet / superconductor and ferromagnet / insulator / superconductor contacts 
  6. to designate and analyze applications for magneto-resistive effects. 


No preconditions in addition to the requirements for the Master’s program in Physics.
