Spinelektronik

What it is about

You learn physical fundamentals and applications of spintronics, in particular magnetoresistive effects (AMR, CMR, GMR, TMR, EMR), spin injection in semiconductors and spin-dependent devices. In the end you will be able to explain these effects, compare them, name relevant material parameters, perform simple transport and tunnel calculations, and analyze applications such as sensors, read heads and MRAM.

What you will be able to do

• Understand and compare magnetoresistive effects (AMR, CMR, GMR, TMR)
• Describe magnetization and magnetoresistance curves of ferromagnetic layers
• Name important ferromagnetic and magnetoelectronic materials with parameters
• Calculate magnetoresistance effects with Boltzmann transport and one-dimensional tunnel theory
• Describe Ferromagnet/Superconductor and Ferromagnet/Insulator/Superconductor contacts
• Analyze application areas of magnetoresistive effects (sensors, hard disk read heads, MRAM)
