    Double magnetic proximity in Fe/Fe0.32V0.68 superlattices 
    Palonen, H.; Magnus, Fridrik; Hjörvarsson, Björgvin (American Physical Society (APS), 2018-10-12)
    The conventional magnetic proximity effect and double-proximity effects were studied in a set of fully coherent high-quality Fe/Fe0.32V0.68 superlattices. Applying a simple model to the saturation magnetization, it is seen that the magnetic proximity ...

    Giant magnetic proximity effect in amorphous layered magnets 
    Thorarinsdottir, Kristbjorg Anna; Palonen, H.; Palsson, G. K.; Hjörvarsson, Björgvin; Magnus, Fridrik (American Physical Society (APS), 2019-05-21)
    Here we study the magnetic proximity effect in amorphous layered magnets of alternating high- and low-Tc materials using magnetometry and polarized neutron reflectivity. By altering the thickness of either the high- or low-Tc layer we are able to extract ...

    Large uniaxial magnetostriction with sign inversion at the first order phase transition in the nanolaminated Mn2GaC MAX phase 
    Novoselova, Iuliia P.; Petruhins, Andrejs; Wiedwald, Ulf; Ingason, Árni Sigurdur; Hase, Thomas; Magnus, Fridrik; Kapaklis, Vassilios; Palisaitis, Justinas; Spasova, Marina; Farle, Michael; Rosen, Johanna; Salikhov, Ruslan (Springer Nature, 2018-02-08)
    In 2013, a new class of inherently nanolaminated magnetic materials, the so called magnetic MAX phases, was discovered. Following predictive material stability calculations, the hexagonal Mn2GaC compound was synthesized as hetero-epitaxial films ...

    Local structure in amorphous Smx Co1−x : a combined experimental and theoretical study 
    George, Sebastian; Kádas, Krisztina; Jönsson, Petra E.; Muscas, Giuseppe; Magnus, Fridrik; Eriksson, Olle; Delin, Anna; Andersson, Gabriella (Springer Science and Business Media LLC, 2020-06-12)
    Using a combination of extended X-ray absorption fine structure measurements, stochastic quenching (SQ) calculations and Voronoi tessellation analysis, the local atomic environments in thin films of amorphous SmxCo1−x (x= 0.10, 0.22 and 0.35) are ...

    Phase Evolution and Microstructure Analysis of CoCrFeNiMo High-Entropy Alloy for Electro-Spark-Deposited Coatings for Geothermal Environment 
    Karlsdóttir, Sigrún; Geambazu, Laura E.; Csaki, Ioana; Þórhallsson, Andri I.; Stefanoiu, Radu; Magnus, Fridrik; Cotrut, Cosmin (MDPI AG, 2019-06-21)
    In this work, a CoCrFeNiMo high-entropy alloy (HEA) material was prepared by the vacuum arc melting (VAM) method and used for electro-spark deposition (ESD). The purpose of this study was to investigate the phase evolution and microstructure of the ...

    Sequential magnetic switching in Fe/MgO(001) superlattices 
    Magnus, Fridrik; Warnatz, T.; Palsson, G. K.; Devishvili, A.; Ukleev, V.; Palisaitis, J.; Persson, P. O. Å.; Hjörvarsson, Björgvin (American Physical Society (APS), 2018-05-24)
    Polarized neutron reflectometry is used to determine the sequence of magnetic switching in interlayer exchange coupled Fe/MgO(001) superlattices in an applied magnetic field. For 19.6 Å thick MgO layers we obtain a 90 ∘ periodic magnetic alignment ...
