Abstract
Measurements of the microwave dielectric properties of Ba6-xSm8+2x/3Ti18O54 solid solutions revealed the existence of a broad maximum in the temperatu re dependence of the permittivity as well as the dielectric loss. Submillim eter-wave frequency measurements confirmed the intrinsic origin of the obse rved anomaly, which could possibly be ascribed to phase transition with unk nown nature in the Ba6-xSm8+2x/3Ti18O54 solid solution. The temperature of the anomaly, which is in the range of 90-120 degrees C, depends on composit ion of Ba6-xSm8+2x/3Ti18O54 and decreases with an increase in x.
