  1. 1. Single-Electron Tunneling Spectroscopy in Magnetic Nanoparticles and Molecular Magnets

    Författare :Lukasz Michalak; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; master equation; magnetic nanoparticles; spin accumulation; molecular magnets; TMR; tunneling magnetoresistance; F-SET; ferromagnetic single-electron transistor; single-electron tunneling; nanomagnetism; spintronics; Coulomb blockade;

    Sammanfattning : This thesis deals with single-electron tunneling in transistor-like devices in which the central electrode is either a metal nanoparticle (possibly ferromagnetic) or a molecular magnet. The investigated systems split into two different categories, depending on the size of the central island. LÄS MER

  3. 2. Spin Transport Studies of Nanoscaled Ferromagnetic Tunneling Devices

    Författare :Ruisheng Liu; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tunneling anisotropic magnetoresistance.; tunneling magnetoresistance; ferromagnetic single electron transistor; spin relaxation; Spin transport;

    Sammanfattning : This thesis presents spin transport studies of ferromagnetic nano-scaled tunneling devices fabricated by atomic force microscopy (AFM) and electron beam lithography (EBL). The thesis covers three main topics: The first topic is a study of spin accumulation (relaxation) in Au nano-structures using Ni/Au/Ni ferromagnetic single electron transistors (F-SETs). LÄS MER

  4. 3. Spin-dependant transport in lateral nano-devices based on magnetic tunnel junctions

    Författare :Mattias Urech; Vladislav Korenivski; Bernard Dieny; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spin diffusion; magnetic tunnel junctions; Physics; Fysik;

    Sammanfattning : This thesis is an experimental study of spin dependent transport in nanoscale ferromagnetic tunnel junction arrays and lateral multi-terminal devices with normal metal and superconducting spin transport channels. Two-, three-, and five-junction arrays have been fabricated in the form of lateral circuits and characterized using variable temperature magneto-transport measurements. LÄS MER
