| Abstract Scope |
Artificial spin ices (ASIs), metamaterials comprised of nanoscale ferromagnetic islands, have emerged as potential candidates for novel forms of computing (e.g. reservoir and neuromorphic). To date, ASIs have been mostly synthesized from permalloy alloys. Multi-principal element alloys (MPEAs) are among several alternative soft magnetic alloys with the potential to exhibit enhanced magnetic properties for ASIs. In addition, ASIs formed from magnetic MPEAs could exhibit frustration at multiple lengths scales. In this study, compositionally combinatorial films of AlxCrFeCoNi were synthesized using magnetron sputtering and characterized to identify those with saturation magnetization similar to permalloy and reduced Gilbert damping. High throughput characterization to identify phases present (2D XRD) and compositions (EDS) was conducted. Saturation magnetization and coercive field were characterized using magnetometry, and Gilbert damping was evaluated from ferromagnetic resonance linewidths. A preliminary discussion of this material system’s impact on ASI’s will be provided. |
