  1. 6. Micromagnetic study of spin Hall nano-oscillator arrays and their synchronization dynamics

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Ari Sigurdsson; [2020]
    Keywords : spintronics; spin Hall nano-oscillators; spin wave; synchronization; micromagnetic modelling.; spinntronik; spinn-Hall nano-oscillatorer; spinn wave; synkronisering; mikromagnetisk modellering.;

    Abstract : Spintronics is the study of electron spins and their utilization in electronic devices. Within this field, spin-based oscillators have shown promise for mi- crowave signal generation as they can operate at high frequencies, are small in scale and are compatible with modern fabrication techniques.

  2. 7. Probing magnetic Dynamics inNanoarrays using AC susceptibility

    University essay from Uppsala universitet/Materialfysik

    Author : Tobias König; [2020]
    Keywords : ;

    Abstract : This project revised a magneto-optical ac susceptometer aiming to improve the experimentalapproach to investigate the magnetization dynamics of magnetic nano arrays.First the experimental setp was equipped with a new Helmholtzcoil which enables strongerAC magnetic eld compared to the installed coils on the system. That includes i.e. READ MORE

  3. 8. Transient Dynamics and Core Tunneling in Vertical Spin-Vortex Pairs

    University essay from KTH/Nanostrukturfysik

    Author : Milton Persson; [2019]
    Keywords : Spin-vortex; ultra fast vortex dynamics; milli-Kelvin temperatures; macroscopic quantum tunneling; Spinnvirvel; ultrasnabb virveldynamik; milli-Kelvin temperaturer; makroskopisk kvanttunnling;

    Abstract : Spin-vortices in vertically spaced pairs of thin elliptical Permalloy nanoparticles are investigated. The two vortex cores with parallel out-of-plane magnetization exhibit a strong monopole-like attraction through the spacer much thinner than the core length, thus forming a bound core-core pair.

  4. 9. Effective Visualization of Magnetization Dynamics.

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Édgar Méndez; [2018]
    Keywords : ;

    Abstract : Simulations on magnetization dynamics are of great interest on current research. Unlike computational fluid dynamics, magnetization dynamics has not received much attention from the visualization community. READ MORE

  5. 10. Micromagnetic simulations of magnetization dynamics in iron-palladium nanostructure arrays

    University essay from Uppsala universitet/Materialfysik

    Author : Agne Ciuciulkaite; [2016]
    Keywords : micromagnetic simulations; magnetization dynamics; iron-palladium circular islands; ferromagnetic resonance;

    Abstract : Previous investigations of FePd circular island arrays have shown the hysteresis-free switching from vortex to collinear magnetic state at high temperatures [1]. This raises interest in the exploration of the temperature and inter-island interaction effect on the magnetization dynamics in this kind of structures. READ MORE
