Gold-iron or gold-iron oxide nano-particles (NPs) are of particular importance because of their bio diagnostic and medicinal applications. Applying either plasma (8.3 kHz) or laser (1064 nm) radiation we produced a kind of Au-Fe nano-composite, in case of plasma a giant gold nano flowers (1-2 000 nm). The product was analysed by EDX and SEM. Mass spectrometry with LDI (laser 337 nm) yields single charged AumFen± (m = 1-35; n = 1-3) clusters. Structures of clusters in neutral and monocharged forms were designed by DFT calculations (ADF; scalar relativistic ZORA geometry optimization). The structures in local minima of potential energy surface always have Fe atoms coordinated to several Au atoms (most often to 4 to 6) and posses few odd electrons (4 to 9).The distances of a Fe nucleus from adjacent Au nuclei lie in the interval 2.5 – 2.7 .
