1. 11. Magnetic State Detection in Magnetic Molecules Using Electrical Currents

   University essay from Uppsala universitet/Materialteori

   Author : Turab Saygun; [2015]
   Keywords : Magnetic Molecules; Nanoscale Systems; Spintronics; Molecular Spin Valve; Quantum Computing; Quantum Dot System; Nanoscale transistor; Nanostructures; Solid State Physics; Many Body Physics; Condensed Matter Physics; Green s Functions;

   Abstract : A system with two magnetic molecules embedded in a junction between non-magnetic leads was studied. In this system electrons tunnel from the localized energy level in region one to the localized energy level in region two generating a flow of electric charge through the quantum dot system.

3. 12. Non-equilibrium dynamics ofa single spin in a tunnel junction

   University essay from Materialteori

   Author : Henning Hammar; [2014]
   Keywords : molecular electronics; spintronics; solid state theory; spin system; quantum computers;

   Abstract : Making spintronic devices is a hot topic for future technical development. In this work the non-equilibrium dynamics of a single spin in a tunnel junction is analyzed and numerically simulated. This is done in order to understand the dynamics of e.g. READ MORE

4. 13. Spin-FET based on InGaAs/InP heterostructure

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Author : Ricardo Moreira Salles De Andrade; [2011]
   Keywords : Spin; Spintronics; Field-effect transistor; Datta-Das transistor; Rashba effect; Low-temperature.; Physics and Astronomy;

   Abstract : A new design based on the spinFET proposed by Datta-Das was fabricated, using a channel defined by etching on a 2DEG material and nanomagnets as top-gates. The magnetotransports properties were measured at low temperatures. READ MORE

5. 14. Domain wall propagation in nanometric layers of (Ga,Mn)(As,P)

   University essay from KTH/Materialvetenskap

   Author : Syed Asad Hussain; [2011]
   Keywords : Domain Wall; Longitudinal Kerr Effect; Ga; Mn As; P ;

   Abstract : Domain wall dynamics is the one of the most interesting topics in the field of Spintronics because of its potential applications in the development of memory devices. These studies of dynamics are particularly focused on dilute magnetic semiconductors (DMS) or ferromagnetic semiconductors, which are believed to be one of the future materials for Spintronics devices.

6. 15. Theoretical study of dilute magnetic semiconductors : Properties of (Ga,Mn)As

   University essay from Institutionen för fysik och astronomi

   Author : Maya Staneva; [2010]
   Keywords : semiconductor; DMS; spintronics; electronic band structure; magnetiska halvledare; spinntronik;

   Abstract : The dilute magnetic semiconductor (Ga,Mn)As , which is the most interesting and promising material for spintronics applications, has been theoretically studied by using Density Functional Theory. First of all, calculations on GaAs were done and it was found that GaAs is a semiconductor with a direct band gap. READ MORE
