Abstract
Ba0.4Sr0.6Ti1−yMnyO3 ceramics showed a bimodal composition of Ba1−xSrxTiO3 and 6H-hexagonal BaTiO3. The Curie peaks of samples are markedly suppressed, broadened and shifted to low temperature with increasing Mn content, and the tunability (T) is decreased. Q values of all samples are above 550. The sample with y = 0.10 exhibits good dielectric properties, with ε′ of 449, Q of 580 (at 1.906 GHz) and T of 3.1%, which make it a potential candidate for the fabrication of tunable microwave devices in wireless communication applications.
