Dielectric behavior of the relaxor ferroelectric Pb(Mg1/3Nb2/3)O3—PbTiO3 solid‐solution system was studied from—50° to 200°C in the 100 to 12 × 109 Hz frequency region, and a broad dielectric relaxation was measured for compositions throughout the system. The relative microwave permittivity of the composition 0.9Pb(Mg1/3Nb2/3)O3·0.1 PbTiO3 decreased by 1 order of magnitude from the 1‐MHz value of 11800, and similar decreases were observed for other compositions in the system. Dielectric loss (tan δ) values ranged from 0.5 to 1.0 at microwave frequency. The temperature of the broad dielectric constant maximum shifts toward higher values with increased frequency.
