From soft to hard magnetic Fe-Co-B by spontaneous strain: A combined first principle and thin film study
Ludwig Reichel, Ludwig Schultz, Darius Pohl +6
In order to convert the well-known Fe-Co-B alloy from a soft to a hard magnet, we propose tetragonal strain by interstitial boron. Density functional theory reveals that when B ato…
Increased magnetocrystalline anisotropy in epitaxial Fe-Co-C thin films with spontaneous strain
Ludwig Reichel, George Giannopoulos, Sandra Kauffmann-Weiss +8
Rare earth free alloys are in focus of permanent magnet research since the accessibility of the elements needed for nowadays conventional magnets is limited. Tetragonally strained…
Electric field control of magnetic exchange coupling
Karin Leistner, Juliane Wunderwald, Norman Lange +5
Electric control of magnetism is a vision which drives intense research on magnetic semiconductors and multiferroics. Recently, also ultrathin metallic films were reported to show…
