Origin of thermally stable ferroelectricity in a porous barium titanate thin film synthesized through block copolymer templating

APL Materials, 2017
A porous barium titanate (BaTiO3) thin film was chemically synthesized using a surfactant-assisted sol-gel method in which micelles of amphipathic diblock copolymers served as structure-directing agents.

BaTiO3–CoFe2O4–BaTiO3 trilayer composite thin films prepared bychemical solution deposition

, 2020
Multiferroic BaTiO3–CoFe2O4–BaTiO3 thin films were synthesized by spin coating of Co(NO3)2–Fe(NO3)3 and Ba(OAc)2–Ti(i-OPr)4 dissolved in a mixture of acetic acid and dimethylformamide.

Magnetoelectric BaTiO3/CoFe2O4 Thin‐Film Meshes for Neuronal Differentiation

Advanced Science, EarlyView.
We engineer an epitaxial BaTiO3/CoFe2O4 magnetoelectric mesh that overcomes boundary‐induced mechanical clamping. Progressively reducing the mechanical constraint, from substrate‐clamped to PDMS‐transferred and ultimately freestanding, enhances magnetic‐to‐electric transduction and strengthens magnetoelectric coupling.

Van der Waals Heterostructures for Next‐Generation Spintronics: Multiferroic‐Mediated Magnetoelectric Properties

Advanced Science, EarlyView.
As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

Artificial Grain Boundaries Created by Freestanding Membrane Transfer Reveal Angle‐Dependent Ferroelectric Switching and Leakage in BaTiO3

Advanced Science, EarlyView.
Artificial grain boundaries are created in BaTiO3$\text{BaTiO}_3$ thin films by freestanding membrane transfer, enabling direct isolation of a single boundary. Local ferroelectric switching and leakage are found to concentrate at the grain boundary, while increasing misorientation systematically enhances conduction.

Hydrothermal synthesis of pure and Dy : BaTiO3 powders at 90 degrees C and their sintering behavior

, 1998
Sub-micron (150-200 nm), monodisperse and spherical powders of pure and Dy-doped (0.8 at%) BaTiO3 have been prepared by "hydrothermal synthesis" at 90 degrees C in an air atmosphere.

Modular Metamaterials for Adaptable MRI Signal Control: Combining Dipole Array With a New Hexagon‐Based Artificial Dielectrics

Advanced Science, EarlyView.
A flexible, hexagonally packed artificial dielectric providing a wide range of effective permittivities (εr ≈ 30–1400) without lumped elements was developed for clinical and ultra‐high‐field MRI. Combined with modular passive‐dipole arrays, the system enables adaptable RF field shaping through electric‐ and magnetic‐dipole tuning.

Magnetic properties of mixed spinel BaTiO3-NiFe2O4 composites

, 2014
Solid solution of nickel ferrite (NiFe2O4) and barium titanate (BaTiO3), (100-x)BaTiO3-(x) NiFe2O4 has been prepared by solid state reaction. Compressive strain is developed in NiFe2O4 due to mutual structural interaction across the interface of NiFe2O4 ...
