• various applications in magnetic technologies [2][3] and electrocatalysis [2][4], derived from the combination of single-element properties which results in enhanced features compared to single-element properties [5]. High-entropy alloy nanoparticles (HEA NPs) constitute a relatively new class of

• alloy nanoparticles is a prerequisite for further development of nanomaterial fabrication methods for applications in heterogeneous catalysis and magnetism. This suitability has been shown in earlier studies for high-entropy alloy nanoparticles, including laser-generated HEA NPs, in the application
