  1. 21. Tailoring the magnetic anisotropy in amorphous FeZr-based thin films on flexible and solid substrates

    Master-uppsats,

    Författare :Matteo Menniti; [2018]
    Nyckelord :amorphous; magnetic; materials; anisotropy; material characterization; iron; cobalt; zirconium; boron; moke; magneto optical; tailoring; material design; flexible; magnetostriction; functional materials; sensor;

    Sammanfattning : In this thesis the magnetic properties of novel amorphous magnetic materials grown on a flexible substrate of polyethylene naphthalate and a silicon wafer have been analyzed and characterized. The analyzed films are two films of amorphous Cobalt-Iron-Zirconium(Co36Fe53Zr11 & Co37Fe55Zr8) grown on the flexible substrate and two films of amorphous (Fe89Zr11) doped with boron (B). LÄS MER

  3. 22. The Magnetic Characterization of Iron-Chrome nanoparticle

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Angga Virdian; [2018]
    Nyckelord :Nanomagnetism; Nanoparticle; Physics and Astronomy;

    Sammanfattning : In this thesis, the intrinsic magnetic characteristic of 10 nm FeCr oxide nanoparticles is studied. The nanoparticles is produced using the method of Spark discharge generation. Scanning electron microscope (SEM) is used to characterize the size distribution and coverage of deposited particle. LÄS MER

  4. 23. Concept and simulation of robotized assembly application

    Magister-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Författare :Hanna Tullock; [2018]
    Nyckelord :Assembly; Collaborative; Concept; Simulation;

    Sammanfattning : Assa OEM is a manufacturer of locks and fittings for windows, doors and cabinets. To be more competitive, automating the production is an advantage. Assa assembles six different types of left and right reversible hinges. One product stands for 80 % of the assembly time on the line. LÄS MER

  5. 24. High Accuracy Speed and Angular Position Detection by Dual Sensor

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Johan Östling; [2018]
    Nyckelord :Sensor; accuracy; camshaft; flywheel; speed sensor; pattern recognition; dual sensor; gmr; giant magnetoresistance; hall effect; universal; ferromagnetic;

    Sammanfattning : For many decades there has been a need in many industries to measure speed and position of ferrous gears. This is commonly done by converting passing gear teeth from trigger wheels to electrical impulses to calculate speed and angular position. LÄS MER

  7. 25. A Comparison of Three Time-stepping Methods for the LLG Equation in Dynamic Micromagnetics

    Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskap

    Författare :Simon Wredh; Anton Kroner; Tomas Berg; [2017]
    Nyckelord :LLG equation; Micromagnetism; Implicit midpoint; Midpoint extrapolation; Projection method;

    Sammanfattning : Micromagnetism is the study of magnetic materials on the microscopic length scale (of nano to micrometers), this scale does not take quantum mechanical effects into account, but is small enough to neglect certain macroscopic effects of magnetism in a material. The Landau-Lifshitz-Gilbert (LLG) equation is used within micromagnetism to determine the time evolution of the magnetisation vector field in a ferromagnetic solid. LÄS MER
