Magnetism, Electronic Structure and Lattice Sites of Fe Ions Implanted into Yttrium

摘要: Using perturbed γ-ray distribution techniques and in-beam Mossbauer spectroscopy, the magnetism, electronic structure, lattice sites of Fe ions implanted into Y have been investigated. About 65% atoms occupy interstitial sites, which come out to be non-magnetic. The remaining fractions is found on substitutional exhibits a nearly Curie-type susceptibility Korringa-type spin dynamics. Local density calculations predict magnetic moment, hyperfine field isomer shift in agreement with experimental results.
