Persistent Uncorrelated Magnetic Domains in Fe/Si Multilayers and their suppression by incorporating 11B4C
Anton Zubayer, Artur Glavic, Naureen Ghafoor +16
This study investigates magnetic domains in Fe/Si and Fe/Si + B4C multilayers using spin flip off-specular polarized neutron reflectometry. The results show that Fe/Si multilayers…
Three-fold Superstructured Superlattice HfN/HfAlN Thin Films for Enhanced Toughness
M. Lorentzon, R. Hahn, J. Palisaitis +4
To simultaneously achieve high hardness and high toughness in protective coatings remains a fundamental challenge. Here, we harness the superlattice architecture to combine Koehler…
Growth Mechanisms and Mechanical Response of 3D Superstructured Cubic and Hexagonal HfAlN Thin Films
M. Lorentzon, N. Takata, D. Depla +10
Transition metal aluminum nitrides are a technologically important class of multifunctional ceramics, however, the HfAlN system remains largely unexplored. We investigate phase sta…
Magnetic hysteresis control in thin film Fe/Si multilayers by incorporation of B4C
Anton Zubayer, Takayasu Hanashima, Jun Sugiyama +12
Magnetic hysteresis properties in Fe/Si multilayers have been studied as a function of the B4C content to control magnetization amplitude, coercivity, and hysteresis tilt, properti…
Optimization of magnetic contrast layer for neutron reflectometry
Anton Zubayer, Fredrik Eriksson, Naureen Ghafoor +3
Neutron reflectivity is a powerful technique for probing density profiles in films, with applications across Physics, Chemistry, and Biology. However, challenges arise when dealing…
Diminished spin-flip reflectivity in stacked multilayers with varying period thicknesses of Fe/Si by incorporating 11B4C
Anton Zubayer, Naureen Ghafoor, Anton Devishvili +8
This study investigates the effects of 11B4C co-sputtering on the structural and optical properties of Fe/Si stacked multilayers, with a focus on neutron supermirror applications.…
