Temperature and electric field response of a dielectric (Ba,Sr)TiO 3 layer between perovskite‐type manganite electrodes
Epitaxial films of ferroelectric (00l)Ba 0.25 Sr 0.75 TiO 3 (BSTO) and ferromagnetic half metal La 0.67 Sr 0.33 MnO 3 were grown by laser ablation, forming a trilayer heterostructure with combined ferroelectric and magnetic properties, on (001)(LaAlO 4 ) 0.3 + (Sr 2 AlTaO 6 ) 0.7 substrates.
