• investigations were prompted by both, fundamental aspects of the magnetism of small particles and clusters [3][4], and an increasing interest by industry, especially in the field of data storage (first magnetic tapes and later hard disk drives) [5][6]. Other important current applications include their use in

• The setup described above enabled us to study the impact of chemical ordering on the magnetism of FePt alloy particles. For this purpose, element-specific hysteresis loops of FePt particles with an average diameter of 5.8 nm were recorded at T = 11 K after different annealing steps in hydrogen plasma
