摘要：

Ba(Mg1/3Ta2/3 )O-3 (BMT) microwave dielectric thin films were successfully synthesized by a modified pulsed laser deposition (PLD) process, which includes low temperature (200degreesC) deposition and high temperature (>500degreesC) annealing. Crystalline structured BMT thin films were obtained when the PLD-deposited films were post-annealed at a temperature higher than 500degreesC in oxygen atmosphere. The characteristics of BMT thin film, including crystallinity, grain size, film roughness, and dielectric properties were improved with annealing temperature, achieving dielectric constant K = 23.5 and dissipation factor tan delta = 0.015 (at 1 MHz) for the 800degreesC-annealed films.
