MÖSSBAUER STUDIES ON DILUTE Tc-(Fe) ALLOYS

DYNAMICAL SUSCEPTIBILITY OF DILUTE (Mo1-xNbx)Fe ALLOYS

-Inelastic neutron scattering has been used to measure the linewidth of the dynamical response of Fe impurities in Mol-,Nb, alloys. The character of the local moment, inferred from its relaxation rate, does not change significantly up to x = 0.15. Between x = 0.15 and x = 0.30 the response decreases rapidly and has disappeared by x = 0.45. The magnetic character of dilute Fe impurities in solid...

Irradiation-induced patterning in dilute Cu–Fe alloys

Article history: Received 9 January 2014 Accepted 24 June 2014 Available online 1 July 2014 Compositional patterning in dilute Cu1 xFex (x 12%) induced by 1.8 MeV Kr irradiation was studied as a function of temperature using atom probe tomography. Irradiation near room temperature led to homogenization of the sample, whereas irradiation at 300 C and above led to precipitation and macroscopic co...

Mössbauer diffractometry on polycrystalline 57 Fe 3

A Mössbauer powder diffractometer was used to measure diffraction patterns from polycrystalline foils of Fe3Al. The intensities of Bragg diffractions were measured as a function of the energy of the incident photon. The bcc fundamental diffractions showed large changes in intensity as the incident energy was tuned through the nuclear resonances. These variations of diffraction intensity with in...

Transport properties of dilute alloys

The review introduces the reader to a theoretical method describing the transport properties of dilute alloys on an ab initio basis. The calculations start from density or spin density functional theory using a Green function formalism to investigate the underlying electronic structure of the ideal and perturbed system on equal footing. The residual resistivity is calculated solving the quasicl...
