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

Cobalt–tin intermetallic compounds of different stoichiometries were studied by means of the perturbed angular correlation (PAC) technique. The hyperfine interaction parameters for 111Cd probes in the crystal lattices of CoSn 2 and Co 3Sn 2 were determined. A T 3/2 temperature dependence of the elec...

Beschreibung
Zusammenfassung:	Cobalt–tin intermetallic compounds of different stoichiometries were studied by means of the perturbed angular correlation (PAC) technique. The hyperfine interaction parameters for 111Cd probes in the crystal lattices of CoSn 2 and Co 3Sn 2 were determined. A T 3/2 temperature dependence of the electric field gradient (EFG) in CoSn 2 compound was found. Due to the thermal interdiffusion in a bilayer Co/Sn sample the formation of the stoichiometric CoSn phase was observed.
