Abstract: | 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+. |
