We have carried out measurements of the magnetic susceptibility, M{umlt o}ssbauer spectra, and specific heat on Gd(Sn{sub 1{minus}{ital x}}In{sub {ital x}}){sub 3}. We observe an oscillatory variation of the antiferromagnetic transition temperature {ital T}{sub {ital N}1} across the series from GdSn{sub 3} ({ital x}=0.0) to GdIn{sub 3} ({ital x}=1.0). For the range of In concentrations 0.265{le}{ital x}{le}0.565, we find a second magnetic transition, at a temperature {ital T}{sub {ital N}2} well below {ital T}{sub {ital N}1}. These measurements along with the temperature dependence of {sup 119}Sn M{umlt o}ssbauer spectra indicate that the ground-state magnetic structure is a type-I antiferromagnetic ordering for the Sn-rich side (0{le}{ital x}{le}0.25) and is a type-II for the very rich In side ({ital x}{r_arrow}1.0). For the range of In concentrations 0.265{le}{ital x}{le}0.565 the magnetic structure is also of type I in the temperature interval {ital T}{sub {ital N}2}{lt}{ital T}{lt}{ital T}{sub {ital N}1}. The magnetic structure for 0.265{le}{ital x}{le}0.565 with {ital T}{lt}{ital T}{sub {ital N}2} and also for 0.565{lt}{ital x}{lt}1.0 with {ital T}{lt}{ital T}{sub {ital N}1} could be a canted antiferromagnetic ordering state. {copyright} {ital 1996 The American Physical Society.}
