DFT calculations of magnetocrystalline anisotropy energy with fixed spin moment
Justyn Snarski-Adamski, Joanna Marciniak, Wojciech Marciniak +2
The development of new-generation permanent magnets is based on experimental efforts and innovative theoretical tools for modeling magnetic properties. Magnetocrystalline anisotrop…
Perpendicular magnetic anisotropy in Au/FeCo/Au ultrathin films: Combined experimental and first-principles study
Justyn Snarski-Adamski, Hubert GÅowiÅski, Justyna RychÅy-Gruszecka +2
Magnetic tunnel junctions with a magnetic layer with perpendicular anisotropy are currently used in computer memories that do not require voltage sustaining. An example of layers w…
Magnetic hardness of hexagonal and orthorhombic FeC, CoC, (Fe-Co)C, and their alloys with boron, nitrogen, and transition metals: A first-principles study
Justyn Snarski-Adamski, MirosÅaw WerwiÅski, Justyna RychÅy-Gruszecka
In this study, we considered a large set of materials that are closely related to orthorhombic FeC (cementite) with the aim of characterizing trends in their intrinsic magnetic…
Giant magnetocrystalline anisotropy energy in Fe--Co alloy under uniaxial compression: first-principles prediction
Wojciech Marciniak, Joanna Marciniak, José Ãngel Castellanos-Reyes +1
Uniaxially strained Fe--Co disordered alloys have emerged as promising candidates for cost-effective rare-earth-free permanent magnets due to their high magnetocrystalline anisotro…
