The different post-breakdown features of CaTiO3 ceramics prepd. by different process well interpret why the enhanced dielec. strength is achieved in the SPS sample. The energy storage d. can be further improved to 11.8 J/cm3 by introducing the amorphous alumina thin films as the charge blocking layer, where the dielec. strength is 1188 kV/cm.

Field induced changes in cycloidal spin ordering and.

Multiferroic La-doped BiFeO3 thin films have been prepared by a sol-gel plus spin-coating process, and the local magnetoelectric coupling effect has been investigated by the magnetic-field-assisted scanning probe microscopy connected with a ferroelectric analyzer. The local ferroelectric polarization response to external magnetic fields is. Multiferroic nanomaterials have attracted great interest due to simultaneous two or more properties such as ferroelectricity, ferromagnetism, and ferroelasticity, which can promise a broad application in multifunctional, low-power consumption, environmentally friendly devices. Bismuth ferrite (BiFeO3, BFO) exhibits both (anti)ferromagnetic and ferroelectric properties at room temperature. Thus.

BiFeO 3, a single-phase multiferroic material, possesses several polymorphs and exhibits a strong sensitivity to strain.Recently, emergent strain engineering in BiFeO 3 thin films has attracted intense interest, which can overcome the confines of traditional strain engineering introduced through the mismatch between the film and substrate. In this review, we discuss. BiFeO3, a single-phase multiferroic material, possesses several polymorphs and exhibits a strong sensitivity to strain.

Raman scattering study of multiferroic BiFeO3 single crystal.

. A large perpendicular exchange bias was observed, arising from the cycloid spin structure of the BiFeO 3. In addition, at room temperature the film displays a larger magnetic moment than BiFeO 3 and YMnO 3, as well as ferroelectricity with good retention capability. Large exchange biasing, controlled by the magnetic field cooling history, will. 3, a well-known room temperature multiferroic, the competition between various exchange interactions manifests itself as non-collinear spin order, i.e., an incommensurate spin cycloid with period 64nm. We report on the stability and systematic expansion of the length of the spin cycloid in (110)-oriented epitaxial Co-doped BiFeO 3 thin ﬁlms.

In this study, we studied the structural properties and ferroelectric characteristics of the pure BeFiO 3 (BFO) and mixed NiTiO 3-BiFeO 3 (NTO-BFO) thin films by the sol-gel method and spin-coating process. We employed atomic force microscopy, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, X-ray diffraction, and transmission electron microscopy to analyze the. There is growing interest in studying the optical properties of multiferroic BiFeO3 (BFO) thin films for optoelectronic applications. In the present work, BFO thin films were prepared by sol-gel spin coating technique and were irradiated using the 15 UD Pelletron accelerator with 100 MeV Au9+ ions at a fluence of 1 × 1012 ions cm-2. The as. Here, we demonstrate cycloidal spin order in 100 nm BiFeO3 thin films through the careful choice of crystallographic orientation, and control of.

Here we report the retention of the spin cycloid in 100 nm thin films of BFO, grown on (110)-oriented SrTiO 3 (STO) substrates with a SrRuO 3 (SRO) bottom electrode. This lifts the previously considered geometrical constraint that the spin cycloid collapses in thin films thinner than ~300 nm grown on STO substrate 23, 24, 28.

The length of the spin cycloid as extracted from line profiles along \ ( [11\bar 2]\) is 67.8 (4.8) nm and 69.7 (5.3) nm for these films, respectively. e RSM maps of. As the BFO film thickness decreases to 180 nm, the grain size decreases, and the surface-to-volume ratio increases. Thus, the effect of the antiferromagnetic-order destruction at the grain surfaces becomes strong, increasing M s value. 4. Conclusions. In this work, we prepared a multiferroic BFO thin film by a simple sol–gel spin-coating method.
