    Sammanfattning : This is a history of theories and theorists of unequal exchange. Starting with mercantilists and Richard Cantillon's theory based on land values, it briefly covers the early Classical economists and Gerald Fitzhugh. LÄS MER

  2. 2. Fabrication and Characterization of magnetometer for space applications

    Författare :Fatjon Qejvanaj; Johan Åkerman; BRAD ENGEL; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; AMR; Magnetic sensor; Ferromagnetic; Antiferromagnetic; NiFe; IrMn; exchange bias.; Physics; Fysik; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : The present rapid increase in the number of space missions demands a decrease in the cost of satellite equipment, but also requires the development of instruments that have low power consumption, low weight, and small size.Anisotropic magnetoresistance (AMR) sensors can answer these needs on account of their small size, weight, and power consumption.

  3. 3. Characterization of Magnetic Nanoscale Systems: From Molecules to Particles and Self-Assembled Chains

    Författare :Claudiu Bulbucan; NanoLund; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Magnetism; Magnetic nanoparticles; Exchange bias; Single molecule magnets; Magnetic nanochains; X-ray magnetic circular dichroism;

    Sammanfattning : This thesis characterizes magnetic nanoscale systems with increasing size and aspect ratio using synchrotron radiation-based spectroscopy and microscopy techniques, combined with conventional magnetometry. The systems studied are molecular magnets, bimagnetic nanoparticles and self-assembled magnetic nanochains. LÄS MER

  4. 4. Solution-Chemical Synthesis of Cobalt and Iron:Zinc Oxide Nanocomposite Films
