  1. 6. Fabrication and characterization of novel nano-magnets

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Louise Lifvenborg; [2020]
    Keywords : nanotechnology; nano-magnets; magnetism; Master s Programme in Materials Engineering; Q; lithography;

    Abstract : Magnetic data storing has been of great interest since 1950 when the first magnetic hard drive was fabricated. A lot has happened since then, but there is still a need for smaller and cheaper devices.  One way to achieve this is by creating nano-sized ferromagnetic areas in a thin film at room temperature, or nano-magnets.

  3. 7. Design and Simulation of Terahertz Antenna for Spintronic Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Nils Eivarsson; Malin Bohman; Emil Grosfilley; Axel Lundberg; [2020]
    Keywords : spintronics; terahertz; THz; antenna; simulation; COMSOL multiphysics;

    Abstract : Spintronics is a spin-electronic field where the electron spinangular momentum, in conjunction with charge, is used to read andwrite information in magnetic sensors and logic circuits, e.g. hard disk drive (HDD), magnetic random access memory (MRAM) and broadband TeraHertz (THz) emitters.

  4. 8. Impact of Surrounding Objects on Inductive Wireless Power Transfer

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Brenda Odhiambo; [2019]
    Keywords : Wireless power transfer; inductive coupling; Qi Specification; effect of metals; Technology and Engineering;

    Abstract : Many new models of smartphones and small electronic devices are using their wireless charging feature as a key selling point. This is due to the convenience of cable-free charging as well as not requiring multiple power adapters for charging different devices. READ MORE

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

    University essay from

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

    Abstract : 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). READ MORE

  6. 10. The Magnetic Characterization of Iron-Chrome nanoparticle

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Angga Virdian; [2018]
    Keywords : Nanomagnetism; Nanoparticle; Physics and Astronomy;

    Abstract : 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. READ MORE
