ABSTRACT:
A thin film composite material comprises barium strontium titanate represented as Ba.sub.1-x Sr.sub.x TiO.sub.3 wherein x is greater than 0.0 but less than or equal to 0.75 and a magnesia-based compound such as MgZrO.sub.3, MgTiO.sub.3, MgAl.sub.2 O.sub.4 and mixtures thereof. The thin film ferroelectric composite is made using pulsed laser deposition and exhibits high tunability, low loss and a low dielectric constant.
