Co-Sn intermetallic phases and their formation at the Co/Sn interface studied with perturbed angular correlation (PAC) method

摘要

Cobalt-tin intermetallic compounds of different stoichiometries were studied by means of the perturbed angular correlation (PAC) technique. The hyperfine interaction parameters for Cd-III probes in the crystal lattices of CoSn2 and Co3Sn2 were determined. A T-3/2 temperature dependence of the electric field gradient (EFG) in CoSn2 compound was found. Due to the thermal interdiffusion in a bilayer Co/Sn sample the formation of the stoichiometric CoSn phase was observed. (C) 1998 Elsevier Science S.A. [References: 22]
