Sketch of Au−Fe NPs formation mechanism by LML for different initial gold content in the Au‐Fe2O3 educt nanoaggregates. For highest Au content, only alloy NPs are obtained. For low Au content, core‐shell morphologies are observed with a Fe‐rich shell. Reprinted with permission from Ref. [45] under a Creative Commons (CC‐BY 4.0) license. Copyright (2019) the Authors.
