Tz. Vitkina et al., Magnetic susceptibility and peculiarities of chemical bond in the AgGa(S1-xSex)(2) solid solutions, CRYST RES T, 35(2), 2000, pp. 229-238
The measurements of magnetic susceptibility of the AgGa(S1-xSex)(2) solid s
olutions with the chalcopyrite structure have been performed and the lattic
e susceptibility separated into the Langevin diamagnetic and the Van Vleck
paramagnetic terms. The obtained data were used to evaluate the character o
f chemical bond in these alloys. The correlations between the parameters of
chemical bond and other physical properties are discussed. It is shown tha
t the investigated solid solutions have preferably ionic character of chemi
cal bond. The Ga-S(Se) (B-C) bonds are found to be stronger than the Ag-S(S
e) (A-C) bonds.
