Abstract Scope |
Artificial spin lattices (ASLs), composed of nanoscale ferromagnetic islands, are emerging as promising materials for advanced computing paradigms like reservoir and neuromorphic computing. While current ASLs typically use permalloy alloys, multi-principal element alloys (MPEAs) offer an intriguing alternative due to their potential for enhanced magnetic properties and swift magnetic fluctuations arising from inherent magnetic frustration. This study investigates Al₀.₂₅CrFeCoNi thin films synthesizing via magnetron sputtering. Comprehensive characterization techniques including XRD, EDS, and FIB/SEM were employed to analyze structure, composition, and thickness. SQUID magnetometry was utilized to examine M-H hysteresis loops and M-T curves in zero-field cooling (ZFC) and field cooling (FC) states, providing insights into magnetization, coercive fields, and transition temperatures. A broadband FMR spectroscopy was used to assess Gilbert damping through resonance linewidth analysis. This thorough evaluation offers valuable insights into the potential of this MPEA as a soft magnetic material for next-generation ASLs and computing applications. |
