Epitaxial BiFeO3 multiferroic thin film heterostructures.
Enhancement of polarization and related properties in heteroepitaxially constrained thin films of the ferroelectromagnet, BiFeO3, is reported. Structure analysis indicates that the crystal structure of film is monoclinic in contrast to bulk, which is rhombohedral. The films display a room-temperature spontaneous polarization (50 to 60 microcoulombs per square centimeter) almost an order of magn...
متن کاملComment on "Epitaxial BiFeO3 multiferroic thin film heterostructures".
Wang et al. (1) recently reported multiferroic behavior, with ferromagnetic and ferroelectric polarizations that are both large at room temperature, in thin strained films of BiFeO 3 (BFO). Although at room temperature, bulk BFO is ferroelectric (2) and antiferromagnetic (3–5), Wang et al. (1) reported that a 70-nm film shows both an enhanced ferroelectric polarization (90 mC cm) and a substant...
متن کاملIn situ TEM analysis of resistive switching in manganite based thin-film heterostructures.
The mechanism of the electric-pulse induced resistance change effect in Au/Pr0.65Ca0.35MnO3/SrTi0.99Nb0.01O3 thin-film samples is studied by means of in situ electrical stimulation inside a transmission electron microscope. A detailed equivalent-circuit model analysis of the measured current-voltage characteristics provides crucial information for the proper interpretation of the microscopy res...
متن کاملDomain wall resistivity in epitaxial thin film
This article reviews our recent experimental studies of domain wall (DW) resistivity in epitaxial transition metal ferromagnetic thin film microstructures with stripe domains. The results are presented and analysed in the context of models of DW scattering and conventional magnetoresistance (MR) effects in ferromagnetic metals. Microstructures of progressively higher magnetic anisotropy and thu...
متن کاملOptical Characterization of Ferromagnetic and Multiferroic Thin-Film Heterostructures
This thesis presents optical characterization of the static and dynamic magnetic interactions in ferromagnetic and multiferroic heterostructures with time-resolved and interface-specific optical techniques. The focus of the thesis is on elucidating the underlying physics of key physical parameters and novel approaches, crucial to the performance of magnetic recording and spintronic devices. Fir...
