The dielectric properties and frequency dispersion associated with a dielectric relaxation were evaluated within the perovskite (1-x)BiScO3-xBa(Mg1/3Nb2/3 O3 solid solution systems (0.7 ≤ x ≤ 1). With increasing BiScO3, the room-temperature dielectric permittivity at low frequency (100 Hz) increased up to 115 at x = 0.7, and a dielectric relaxation phenomenon was evident. Relaxation parameters were analyzed using several Arrhenius-type equations, and the microwave dielectric property measurement using rectangular wave-guide method enabled confirmation of the extrapolated value of the Arrhenius plot. The result of the microwave dielectric property measurement was also checked with J-function fitting based on the frequency-dependent Gaussian distribution of the associated dielectric loss data at low frequency.
