Epitaxial Ba[sub 1[minus][ital x]]K[sub [ital x]]BiO[sub 3] thin films have been grown by pulsed-laser deposition at temperatures as low as 400 [degree]C. Films have been grown on (100) MgO and SrTiO[sub 3] with [ital T][sub [ital c]]([ital R]=0)=19.5 K and transition widths less than 1 K. Four circle x-ray diffraction shows that these epitaxial films are mostly (00[ital l]) oriented with good in-plane epitaxy. We find that, especially for growth on (100) MgO, an initial epitaxial layer of BaBiO[sub 3] grown at 600 [degree]C significantly improves the properties of the Ba[sub 1[minus][ital x]]K[sub [ital x]]BiO[sub 3] films.
