Аннотация:Short-range order, due to the strong interatomic Al-Fe interaction, is the key factor governing the unexpected quick change of the magnetic properties of Fe0.75-xAl0.25+x alloys over a narrow range of Al concentration, x = 0.0-0.05. The sharp transition from ferromagnetism to spin-glass magnetic structure is the result of the generation of a high (non-statistical) concentration of Fe sites with a large number of Al nearest-neighbors.
