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 Głowiński, Justyna Rychły-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, Mirosław Werwiński, Justyna Rychły-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…
Boundary-induced phase in epitaxial iron layers
Anna L. Ravensburg, Mirosław Werwiński, Justyna Rychły-Gruszecka +9
We report the discovery of a boundary-induced body-centered tetragonal (bct) iron phase in thin films deposited on MgAlO () substrates. We present evidence for thi…
Iron and gold thin films: first-principles study
Justyna Rychły-Gruszecka, Hubert Głowiński, Justyn Snarski-Adamski +2
Using density functional theory, we carried out systematic calculations for a series of ultrathin iron layers with thicknesses ranging from one atomic monolayer to eleven monolayer…
First-principles study of the magnetic anisotropy of ultrathin B-, C-, and N-doped FeCo films
Joanna Marciniak, Mirosław Werwiński, Justyna Rychły-Gruszecka
Iron-based layered systems are of great interest because of their ability to tune effective material parameters such as magnetic anisotropy energy (MAE). The influence of the cryst…
