Gd1–xLaxScO3, Gd1–xLaxInO3and Gd1–xLaxGaO3solid solutions were synthesized by the ceramic method, their crystal structure and magnetic properties were investigated. It has been established that the range of solid solutions Gd1–xLaxScO3(0.0 < х ≤1.0), Gd1–xLaxInO3(0.2  х 1.0) and Gd1–xLaxGaO3(0.5  х 1.0) with the structure of orthorhombically distorted perovskite was formed. The effective magnetic moment of the Gd 3+ ion (µef, Gd 3+) for Gd1–xLaxScO3solid solutions with x= 0.10; 0.50 is equal to 7.76 В; 7.61 µВ, respectively and it is slightly lower than the theoretical value ef. theor, Gd 3+= 7.94 µВ, and for x= 0.75; 0.90 it is practically equal to the theoretical value. For Gd1–xLaxGaO3solid solutions with x= 0.8; 0.9 the effective magnetic moment ef, Gd 3+ is 7.90 В; 7.99 В, respectively, and it is close to the theoretical value 7.94 В. For Gd1–xLaxInO3solid solutions the effective magnetic moment ef, Gd 3+ varies without certain dependence in the interval from 6.91 Вto 7.54 µВand is lower than theoretical value эф. теор, Gd 3+.
