  5. 23. Engineering Magnetic Droplets in Nanocontact Spin-Torque Nano-Oscillators

    Author : Sheng Jiang; Johan Åkerman; Dario Arena; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Magnetic Droplet; Magnetic Tunnel Junction; Perpendicular Magnetic Anisotropy; Spin-torque Nano-Oscillators; Spin-Valve.; Physics; Fysik;

    Abstract : Spin-torque nano-oscillators (STNOs) are nanoscale spintronic devices capable of generating highly tunable broadband microwave signals. In this thesis, I study nanocontact (NC)-based STNOs using strong perpendicular magnetic anisotropy(PMA) free layers, where a novel magnetic soliton—a magnetic droplet—exists. READ MORE

  6. 24. Spin Torque and Spin Hall Nano-Oscillators with Single Magnetic Layers

    Author : Philipp Dürrenfeld; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spintronics; Spin Torque Oscillators; Spin Hall Effect; Synchronization;

    Abstract : Spin-torque oscillators (STOs) are capable of producing tunable broadband high-frequency signals within a nanometer-sized region. In this thesis, novel designs for STOs will be discussed; the common theme of these designs will be their use of only one ferromagnetic (FM) material. READ MORE

  7. 25. Modeling, Control and Optimization of theTransient Torque Response in DownsizedTurbocharged Spark Ignited Engines

    Author : Oscar Flärdh; Håkan Hjalmarsson; Jonas Mårtensson; Per Tunestål; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engine modeling; Engine control; Transient torque response; Downsizing; Transient optimization;

    Abstract : Increasing demands for lower carbon dioxide emissions and fuel consumption drive technological developments for car manufacturers. One trend that has shown success for reducing fuel consumption in spark ignited engines is downsizing, where the engine size is reduced to save fuel and a turbocharger is added to maintain the power output.
