Single‐crystal layers of 0.65Pb(Mg 1/3 Nb 2/3 )O 3 ·0.35PbTiO 3 (PMN‐35PT) were grown heteroepitaxially on {001}‐BaTiO 3 template crystals. A {001}‐BaTiO 3 crystal was embedded in a fine‐grained matrix of PMN‐35PT containing excess PbO and heated between 950° and 1150°C for 0–5 h. The initial growth of the PMN‐35PT on the {001} surface and the growth of the matrix grains both displayed a t 1/3 dependence which is characteristic of diffusion‐controlled growth. Growth was limited to ∼100–150 μm due to the significantly reduced driving force at longer times because of matrix coarsening and porosity evolution.
