    Effect of atomic ordering on the magnetic anisotropy of single crystal Ni80Fe20 
    Kateb, Movaffaq; Gudmundsson, Jon Tomas; Ingvarsson, Snorri (AIP Publishing, 2019-03-08)
    We investigate the effect of atomic ordering on the magnetic anisotropy of Ni80Fe20 at.% (Py). To this end, Py films were grown epitaxially on MgO(001) using dc magnetron sputtering (dcMS) and high power impulse magnetron sputtering (HiPIMS). Aside ...

    Experimental identification of two distinct skyrmion collapse mechanisms 
    Muckel, Florian; von Malottki, Stephan; Holl, Christian; Pestka, Benjamin; Pratzer, Marco; Bessarab, Pavel; Heinze, Stefan; Morgenstern, Markus (Springer Nature, 2021-01-04)
    Magnetic skyrmions are key candidates for applications in memory, logic and neuromorphic computing. An essential property is their topological protection that is caused by the swirling spin texture and described by a robust integer winding number. ...

    Fabrication and characterization of Si1−xGex nanocrystals in as-grown and annealed structures: a comparative study 
    Sultan, Muhammad Taha; Maraloiu, Adrian Valentin; Stavarache, Ionel; Gudmundsson, Jon Tomas; Manolescu, Andrei; Teodorescu, Valentin Serban; Ciurea, Magdalena Lidia; Svavarsson, Halldor (Beilstein Institut, 2019-09-17)
    Multilayer structures comprising of SiO2/SiGe/SiO2 and containing SiGe nanoparticles were obtained by depositing SiO2 layers using reactive direct current magnetron sputtering (dcMS), whereas, Si and Ge were co-sputtered using dcMS and high-power impulse ...

    The optical control of phase locking of polariton condensates 
    Chestnov, I Y; Kavokin, A V; Yulin, A V (IOP Publishing, 2019-11-01)
    The phase and the frequency of an exciton polariton condensate excited by a nonresonant pump can be efficiently manipulated by an external coherent light. Being tuned close to the resonance with the condensate eigenfrequency, the external laser light ...

    Optimal Control of Magnetization Reversal in a Monodomain Particle by Means of Applied Magnetic Field 
    Kwiatkowski, Grzegorz J.; Badarneh, Mohammad H. A.; Berkov, Dmitry V.; Bessarab, Pavel (American Physical Society (APS), 2021-04-29)
    A complete analytical solution to the optimal reversal of a macrospin with easy-axis anisotropy is presented. An optimal control path minimizing the energy cost of the reversal is identified and used to derive the time-dependent direction and amplitude ...
