  1. 1. Magnetization dynamics in bistable systems

    University essay from Uppsala universitet/Materialfysik

    Author : Sven Backlund; [2023]
    Keywords : magnetism; magneto-optics; magnetization dynamics;

    Abstract : The magnetization dynamics in ferromagnetic materials will depend on the specific shape of the system’s energy landscape. In most systems, the energy landscapes can be approximated as paraboloids, resulting in a typical ellipti- cal precession of the magnetization. READ MORE

  3. 2. A study of optical and structural properties of spin-coated V2O3 thin films on sapphire substrates

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Jennifer Silander; [2022]
    Keywords : Optical properties; transmittance; FTIR spectrometry; scanning electron microscopy; x-ray diffraction; metal-insulator transition; crystalline material; sol-gel; spin-coating; vanadium oxide; infrared light;

    Abstract : Many transition metal oxides exhibit a Metal-Insulator Transition (MIT). This is an interesting phenomenon where the material undergoes a structural phase transition, and the electronic charge is redistributed in the crystal lattice. READ MORE

  4. 3. Small Satellite Design for High Sensitivity Magnetic Measurements

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Noel Sebastian Janes; [2022]
    Keywords : Magnetic Cleanliness; FORESAIL; CubeSats; High Sensitivity Magnetic Measurements; Small Satellite;

    Abstract : The magnetic cleanliness of a spacecraft during magnetic measurements is an important aspect in the design of many space science missions. The adequate reduction or removal of the spacecraft's magnetic disturbance plays a vital role in allowing the ambient magnetic field to be measured with the required accuracy. READ MORE

  5. 4. Reaction Wheel Performance Characterisation and Assessment of Electromagnetic Interactions with Magnetic Torquers

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Leonie Sander; [2021]
    Keywords : Reaction Wheel; Magnetic Torquers; Electromagnetism; Space Mechanism; Attitude Control;

    Abstract : Having an in-depth knowledge on the performance characteristics of space mechanisms in flight operation, with special attention to nominal vs. anomalous performance, is vital for mission success. READ MORE

  6. 5. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Holmér; [2021]
    Keywords : ;

    Abstract : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.
