“…With increasing doses the ordered phase as well as the nonmagnetic component is enhanced. This two-phase region already observed in particle-irradiated Invar alloys 8 has also been observed in meteorites 2,3 and has been considered as the equilibrium state. The CEMS results obtained for a sample of the Santa Catharina meteorite ͑Fig.…”

We investigated the effect of noble gas irradiation ͑He, Ne, and Xe͒ on Fe-Ni multilayers with a very thin modulation and nominal composition in the Invar region Fe 0.63 Ni 0.37 . The evaluation of the formation/stability of the Fe-Ni phases formed under irradiation with different ions and doses was followed by conversion electron Mössbauer spectroscopy. The magnetic hysteresis curves were also obtained in order to correlate the hyperfine pattern with magnetic properties. The as-deposited sample reveals mainly the characteristic ␣-Fe while He-and Ne-irradiated samples clearly show a phase transformation with segregation of ␥-FeNi phases with different Ni concentrations, a magnetic atomically ordered phase ͑ϳ50% Ni͒, and a nonmagnetic phase ͑р30% Ni͒. However, mixing with Ne is more effective than with He for similar doses. The results obtained with Xe showed a large distribution of hyperfine fields similarly to previous results reported for Kr ͓C.

“…As a result, the ordered phase grains are produced within the Fe film. These formation mechanisms may be similar to the formation of the tetrataenite phase by neutron irradiation (NEEL et al, 1964) or high energy electron irradiation (CHAMBEROD et al, 1979) of taenite. The above mechanism can be considered as an artificial acceleration of the diffusion process of Ni atoms through the FeNi crystal lattice.…”

“…A single crystal of ordered FeNi was first produced by the neutron irradiation of a 1964). The artificial formation of tetrataenite has also been experimentally demonstrated by irradiating a disordered FeNi specimen by an electron beam (CHAMBEROD et al, 1979).…”

“…17) When they collide with each other on a substrate, Fe and Ni clusters are neither fragmented nor coalesced at interfaces: Fe and Ni clusters randomly coexist on the substrate. 34) Many phase diagrams reported for Fe 1ÀX Ni X alloys to this day clearly indicate that Fe 1ÀX Ni X alloys are classified into an miscible system: 18,[35][36][37][38][39][40][41][42] bcc Fe-rich solid solution, AuCu 3 -type ordered FeNi 3 and fcc Ni-rich solid solution are the ground state structures, while Cu 3 Au-type ordered Fe 3 Ni and CuAu-type ordered FeNi have been obtained in meteorites, fine particles and neutron-or electron-irradiated specimens. On the contrary, the present Fe/Ni nano-hybrid material is a nano-scale heterogeneous mixture of bcc Fe and fcc Ni grains.…”

Fe and Ni clusters have been simultaneously deposited on substrates using an improved plasma-gas-condensation cluster deposition apparatus, and investigated by transmission electron microscopy, X-ray photoelectron spectroscopy and magnetometry. In these Fe/Ni cluster hybrids Fe and Ni clusters are randomly mixed, where bcc Fe and fcc Ni diffraction rings are detected, and their lattice constants are almost same as those of pure Fe and Ni metals. The peak positions of core-levels, Fe-2p 3=2 and Ni-2p 3=2 lines, of Fe/Ni cluster hybrids are similar to those of pure Fe and Ni clusters. Since Fe and Ni are miscible with each other in bulk, equilibrium and film specimens, no nano-scale heterogeneity can be attained by other methods. Therefore, present results demonstrate formation of novel Fe/Ni nano-hybrid materials.
