X-ray Fractional Orbital Angular Momentum from Coherent Magnetic Scattering
P. D. Montgomery, J. S. Woods, M. R. McCarter +10
Artificial spin ice (ASI) based on a square lattice with a topological defect are known to generate orbital angular momentum (OAM) in diffracted X-ray beams. A previous investigati…
Thermal Effects on Damping Determination of Perpendicular MRAM Devices by Spin-Torque Ferromagnetic Resonance
H. J. Richter, G. Mihajlović, R. V. Chopdekar +5
We report device level damping measurements using spin-torque driven ferromagnetic resonance on perpendicular magnetic random-access memory (MRAM) cells. It is shown that thermal a…
Coupling-dependent antiferromagnetic-ferromagnetic ordering in a pinwheel artificial spin ice
Anders Strømberg, Einar Digernes, Rajesh Vilas Chopdekar +2
Nanopatterned magnetic thin films offer a platform for exploration of tailored magnetic properties such as emergent long-range order. A prominent example is artificial spin ice (AS…
Quantifying the Topology of Magnetic Skyrmions in three Dimensions
David Raftrey, Simone Finizio, Rajesh V. Chopdekar +7
Magnetic skyrmions have so far been treated as two-dimensional spin structures characterized by a topological winding number describing the rotation of spins across the skyrmion. H…
Dative epitaxy of commensurate monocrystalline covalent-van der Waals moiré supercrystal
Mengying Bian, Liang Zhu, Xiao Wang +17
Realizing van der Waals (vdW) epitaxy in the 80s represents a breakthrough that circumvents the stringent lattice matching and processing compatibility requirements in conventional…
Entropy-driven order in an array of nanomagnets
Hilal Saglam, Ayhan Duzgun, Aikaterini Kargioti +14
Long-range ordering is typically associated with a decrease in entropy. Yet, it can also be driven by increasing entropy in certain special cases. We demonstrate that artificial sp…
