“…The values reported for nickel by Salama and Alers (1967), for copper by Hiki and Granato (1966) and for a CO-32 at% Ni alloy by Weston and Granato (1975) are roughly similar to each other. The values of the volume derivatives corresponding to the measurements on nickel by Salama and Alers (2 In B/2 In V ) , = -5.15 (2 In CIS In V ) , = -3.49 (2 In C'/2 In V ) , = -2.29 were used in the present analysis for the whole series of alloys.…”

“…According to measurements on ferromagnetic Fe-Co alloys (McSkimin et al 1972), on ferromagnetic CO-Ni alloys (Leamy andWarlimont 1970, Weston andGranato 1975) and on a paramagnetic Cr-Ni alloy (Lenkkeri 1981), the values of C and B seem to lie on a fairly smooth curve. They differ considerably from the results on the Fe-Ni system by Hausch and Warlimont (1973), Claridge (1968) and Einspruch and Claiborne (1964).…”

The composition dependence of the elastic moduli E, C and C' of FCC transition metal alloys is analysed by separating it into a contribution from the change in the atomic volume and an intrinsic contribution of the electron concentration X. When the volume contribution is taken into account. there are no great differences in the X dependence of B and C in different alloy systems. Differences in the intrinsic X dependence of C' in different alloys seem to arise from magnetic effects. The values of C and C' are anomalously low in alloys with X in the neighbourhood of 8.8. B is relatively insensitive to changes in X except in the regions X < 7.7 and 8.6 < X < 8.9 where it decreases with decreasing X . The temperature dependence of all the moduli is also anomalous in these regions of X.

Inapplicability of Martin transformation to elastic constants of zinc-blende and wurtzite group-III nitride alloys

The applicability of the Martin transformation [R. M. Martin, Phys. Rev. B 6, 4546 (1972)] to the elastic constants of wurtzite and zinc-blende group-III nitride alloys is examined using density functional theory calculations. The composition dependencies of the elastic constants in InGaN, AlGaN, and InAlN are determined by means of ab-initio calculations and compared with the results obtained from the Martin's method. A detailed analysis reveals that the Martin transformation can approximate reasonably well the dependence of the elastic constants on composition in wurtzite InGaN alloys, except for the case of C 33 where it predicts too small bowing. However, it fails to reproduce correctly the composition dependencies of C 13 and C 33 in wurtzite InAlN and C 13 , C 33 , and C 44 in wurtzite AlGaN. In order to identify the origin of the failure of the Martin transformation, the effective elastic constants of strained wurtzite alloys with the ideal value of the lattice axial ratio c/a have been investigated. It is shown that these effective elastic constants are significantly closer to the elastic constants predicted by the Martin's method which indicates that the breakdown of the Martin transformation in group III nitride alloys is partially caused by the deviation of the c/a axial ratio from the ideal value.

A study of the phonon dispersion relation in a Co0.65Ni0.35 alloy shows some novel features, which may be connected to the transition from the f.c.c. to the h.c.p. phase, which is expected at lower temperatures. In fact, in the study of the [ζζζ] T branch in the f.c.c. phase the presence of extra phonon peaks is observed at intermediate q‐values, though the static f.c.c. phase cannot allow for the presence of a new branch. It is believed that a softened optical branch of the h.c.p. phase which interacts with the acoustic branch of the f.c.c. phase may cause the observed phonon structure.
