Abstract:

Recently, large phase-change magnetoelectric response has been anticipated by a first-principles investigation of phases in the BiFeO3–BiCoO3 perovskite binary system, associated with the existence of a discontinuous morphotropic phase boundary (MPB) between multiferroic polymorphs of rhombohedral and tetragonal symmetries. This might be a general property of multiferroic phase instabilities, and a novel promising approach for room temperature magnetoelectricity. We review here our current investigations on the identification and study of additional material systems, alternative to BiFeO3–BiCo

Abstract:

F doping BiFeO3-xFx (x=0, 0.02, 0.04, 0.06, 0.08) thin films were successfully fabricated on ITO/glass substrates by sol-gel method. X-ray diffraction analysis indicated that the un-doped BiFeO3 and F doping BiFeO3 thin films presented rhombohedral structure with the space group R3c. F-doping is found to significantly enhance the dielectric constant and decrease the leakage current density for x=0.08 compared with x=0. This study provides direct evidence that the multiferroic characteristics of BiFeO3 are sensitive to the anion doping, such as F, providing a convenient alternative to manipulat

Multiferroic materials have attracted significant research attention due to their technological potential for applications as multifunctional devices.

Abstract:

Metalorganic decomposition and coprecipitation from aqueous solution have been used to synthesize thin film and bulk bismuth ferrite (BiFeO3) with perovskitestructure. X-ray diffraction, thermomagnetic analysis, and scanning electron microscopy were used to analyze the material and identify spurious phases. The magnetic characterization at room temperature revealed remarkable differences between bulk and film samples. The results show that in BiFeO3 bulk ceramics, spontaneous magnetization is not observed at room temperature. Nevertheless, in thin films, a well-defined ferromagnetic behavior i

Abstract:

Nanometer-scale 3D imaging of materials properties is critical for understanding equilibrium states in electronic materials, as well as for optimization of device performance and reliability, even though such capabilities remain a substantial experimental challenge. Tomographic atomic force microscopy (TAFM) is presented as a subtractive scanning probe technique for high-resolution, 3D ferroelectric property measurements. Volumetric property resolution below 315 nm3, as well as unit-cell-scale vertical material removal, are demonstrated. Specifically, TAFM is applied to investigate the size de

Abstract <strong>Objectives:</strong> The present study focuses on developing La-doped BiFeO3 multiferroic materials for dielectric absorber applications. <strong>Methods:</strong> The samples are characterized by X-ray Diffractometer (XRD). Further, the morphology is examined using field emission electron microscopy (FESEM) and Transmission Electron Microscopy (TEM). The dielectric parameters and ac-electrical parameters are carried out by impedance spectroscopy. The magnetic properties are studied using a vibrating sample magnetometer VSM, P-E loop. <strong>Findings:</str

This work presents an elaborate study of the effect in the structural and magnetic of [Formula: see text] ([Formula: see text], 0.05, 0.10, 0.15, 0.20, 0.25) multiferroic materials, synthesized via a sol-gel auto-combustion method. The synthesized materials are found to have structural distortion in the rhombohedral R3c structure as observed by X-ray diffraction (XRD). Other diffraction peaks were attributed to the second phase [Formula: see text]. The Mossbauer spectra (MS) of [Formula: see text] ([Formula: see text], 0.05, 0.10, 0.15) are fitted with a sextet and a doublet, and the presence

Abstract:

Multiferroic La-doped Bi1-xLaxFeO3 thin films were prepared on conductive indium tin oxide (ITO)/glass substrates through a simple sol-gel process. The crystal structure of La-doped Bi1-xLaxFeO3 thin films annealed at different temperature was determined to be rhombohedral of R3m space and free of secondary phases. The grain size of La-doped BiFeO3 thin films tends to become larger and the grain boundary is gradually ambiguous compared to pure BiFeO3. The double remanent polarization 2Pr of Bi0.9La0.1FeO3 thin film annealed at 500°C is 6.66 µC/cm2, which is slightly improved than that of pure

Abstract:

Though semiconductor technology has advanced significantly in miniaturization and processor speed the “ideal” nonvolatile memory - memory that retains information even when the power goes is still elusive. There is a large demand for non-volatile memories with the popularity of portable electronic devices like cell phones and note books. Semiconductor memories like SRAMs and DRAMs are available but, such memories are volatile. After the advent of ferroelectricity many materials with crystal structures of Perovskite, pyrochlore and tungsten bronze have been derived and studied for the applicati
