Abstract

Abstract Mossbauer effect studies of 57Fe embedded in solid argon (Fe at° = 0.5 at 16K depict the presence of a non-magnetic component with IS = 0.38(4) mm.s -1 and QS = 1.08(7) mm.s -1 which was assigned to Fe 3. The relatively large abundance of Fe 3 with respect to the larger clusters characterized by their magnetic splitting is attributed to the fast quenching of surface diffusion. This is manifested by the presence of Fe 2 dimers highly oriented parallel to the surface. From the relatively small value of QS and the IS it is concluded that the Fe 3 has a triangular structure.
