Summary
The subject is based on current state of quickly evolving field of spintronics, i.e. electronics employing electron's spin. The subject is covering most directions of today's spintronics. The subject starts with definition of spin-polarized current and spin accumulation. Then, generation of spin-polarized current in non-magnetic materials is discussed, using spin injection and spin-pumping. Furthermore, we discuss the most important magnetoresistive effects (AMR, GMR, TMR), as well as spin transfer. Then, we discuss prototypical examples of using those effects in lateral structures and industrial applications. Finally, a short introduction to spin-calorimetry and to materials used in spintronics is provided.
