The improvement of applications concerning CMOS technology is becoming a difficult task, due to physical and technology constrains, such as quantum effects or miniaturization below few nanometers. In order to overcome the related increasing of the power dissipation and rising of the costs, beyond-CMOS technologies have been attracted the attention of recent researches. This thesis explores the basics of one promising beyond-CMOS technology: Racetrack Logic. It is a spintronic technology that can be used for efficient data storaging, thanks to important properties like non-volatility and low power operation, allowing at the same time logic-in-memory. The building block of Racetrack Memories is the motion of magnetic textures into a sub-micron ferromagnetic track, thanks to a current directly injected into the track.
