Substrate-imposed strain engineering of multiferroic properties in BCZT/LCMO bilayer heterostructures
Source abstract
Abstract
Abstract Ba0.85Ca0.15Zr0.9Ti0.1O3/La0.67Ca0.33MnO3 (BCZT/LCMO) bilayer epitaxial heterostructures were deposited on LaAlO3 (LAO), (LaAlO3)0.3(Sr2AlTaO6)0.7 (LSAT) and SrTiO3 (STO) single-crystalline substrates by using pulsed laser deposition, to investigate the substrate-imposed strain engineering of multiferroic properties. The epitaxial growth and the strain state of the as-deposited bilayer heterostructures were determined by X-ray reciprocal space mapping analysis. Results showed that the substrate-imposed strain engineering could turn the multiferroic properties by modulating the polarization switching and domain wall motion of the bilayer heterostructures. The optimal dielectric, ferroelectric and piezoelectric performances were obtained in the bilayer heterostructure deposited on STO substrate while an improved saturated magnetization was achieved in the bilayer heterostructure deposited on LAO substrate. The maximum magnetoelectric coupling was obtained in the bilayer heterostructure deposited on STO substrate with αE31 value of 61.2 mV/cm·Oe.
