Rp. Vaningen et al., FORMATION OF CRYSTALLINE AGXNI1-X SOLID-SOLUTIONS OF UNUSUALLY HIGH SUPERSATURATION BY LASER-ABLATION DEPOSITION, Physical review letters, 72(19), 1994, pp. 3116-3119
Laser ablation was used in a vapor quenching method to deposit thin Ag
-Ni films at room temperature. The films contained substantial amounts
of a polycrystalline nonequilibrium AgxNi1-x solid solution, as evide
nced by x-ray and electron diffraction. The unusually high degree of s
upersaturation attained (up to 44 at.% Ag) has not been observed befor
e for a system exhibiting such a strong demixing behavior. The x-ray d
iffraction sin2psi method was employed to determine the strain-free la
ttice parameter of the solid solution. The solid solution decomposed b
y heating the film.
