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 کاملSingle-domain multiferroic BiFeO3 films
The strong coupling between antiferromagnetism and ferroelectricity at room temperature found in BiFeO3 generates high expectations for the design and development of technological devices with novel functionalities. However, the multi-domain nature of the material tends to nullify the properties of interest and complicates the thorough understanding of the mechanisms that are responsible for th...
متن کاملDirected self-assembly of epitaxial CoFe2O(4)-BiFeO3 multiferroic nanocomposites.
CoFe(2)O(4) (CFO)-BiFeO(3) (BFO) nanocomposites are an intriguing option for future memory and logic technologies due to the magnetoelectric properties of the system. However, these nanocomposites form with CFO pillars randomly located within a BFO matrix, making implementation in devices difficult. To overcome this, we present a technique to produce patterned nanocomposites through self-assemb...
متن کاملOptical Properties of Multiferroic BiFeO3 Films
Lightwave communication systems are predominantly used for handling high-speed data traffic. Long-distance ground-based systems particularly depend on optical fibers. Several business and research facilities employ direct fiber connections, and fiber to the home (FTTH) technology is foreseeable in the near future. These developments are driven particulary by the high demand for bandwidth necess...
