  3. 2. Fabrication and Characterization of Nanocontact Spin-Torque Oscillators

    Författare :Sohrab Redjai Sani; Johan Åkerman; Brad Engel; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spin-torque oscillators; phase locking; spin wave; giant magnetoresistance; spin transfer torque; thin films.;

    Sammanfattning : The manufacturing of nanocontact-based spin-torque oscillators (NC-STOs)has opened the door for spintronic devices to play a part as active microwaveelements. The NC-STO has the capability of converting a direct current intoa microwave signal, and vice versa, by utilizing the spin transfer torque (STT)in ferromagnetic multilayer systems. LÄS MER
