Interfacial strain effects in epitaxial multiferroic heterostructures of PbZrxTi1−xO3∕La0.7Sr0.3MnO3 grown by pulsed-laser deposition

Ferroelectric PbZrxTi1−xO3 and ferromagnetic La0.7Sr0.3MnO3 films were grown on SrTiO3(100) substrates in order to fabricate multiferroic epitaxial heterostructures. Multilayers of PbZr0.2Ti0.8O3∕La0.7Sr0.3MnO3 with 5nm thin individual layers preserve good magnetic properties and have a transition t...

Zusammenfassung:Ferroelectric PbZrxTi1−xO3 and ferromagnetic La0.7Sr0.3MnO3 films were grown on SrTiO3(100) substrates in order to fabricate multiferroic epitaxial heterostructures. Multilayers of PbZr0.2Ti0.8O3∕La0.7Sr0.3MnO3 with 5nm thin individual layers preserve good magnetic properties and have a transition temperature of ∼320K. The variation of the magnetic coercive field of thin La0.7Sr0.3MnO3 films, sandwiched between PbZrxTi1−xO3 films of increasing Zr content in the same epitaxial heterostructure, demonstrates the influence of the interfacial biaxial strain.
