Title: Magnetoelectricity of CoFe₂O₄ and tetragonal phase BiFeO₃ nanocomposites prepared by pulsed laser deposition

Abstract

The coupling between the tetragonal phase (T-phase) of BiFeO₃ (BFO) and CoFe₂O₄ (CFO) in magnetoelectric heterostructures has been studied. Bilayers of CFO and BFO were deposited on (001) LaAlO₃ single crystal substrates by pulsed laser deposition. After 30 min of annealing, the CFO top layer exhibited a T-phase-like structure, developing a platform-like morphology with BFO. Magnetic hysteresis loops exhibited a strong thickness effect of the CFO layer on the coercive field, in particular along the out-of-plane direction. Magnetic force microscopy images revealed that the T-phase CFO platform contained multiple magnetic domains, which could be tuned by applying a tip bias. Here, a combination of shape, strain, and exchange coupling effects are used to explain the observations.

Electrical and magnetic properties of multiferroic BiFeO{sub 3}/CoFe{sub 2}O{sub 4} heterostructure

Journal Article Zheng, R Y ; Wang, J ; Ramakrishna, S - Journal of Applied Physics

To realize a magnetoelectric heterostructure with desired ferroelectric and magnetic properties, a heterostructure consisting of BiFeO{sub 3} (BFO)/CoFe{sub 2}O{sub 4} (CFO) layers has been grown on SrRuO{sub 3} buffered Pt/TiO{sub 2}/SiO{sub 2}/Si substrate by rf sputtering. X-ray diffraction shows that the BFO and CFO phases have been successfully retained in the heterostructure. Grain growth of the CFO phase was enhanced on top of the BFO layer. The heterostructure exhibits both ferroelectric and magnetic behaviors at room temperature. Its remanent polarization (2P{sub r}) is measured to be {approx}146 {mu}C/cm{sup 2} and the coercive field (2E{sub c}) is {approx}1803 kV/cm, while themore »« less

Structure, Ferroelectricity, and Magnetism in Self‐Assembled BiFeO ₃ –CoFe ₂ O ₄ Nanocomposites on (110)‐LaAlO ₃ Substrates

Journal Article Tian, Guo ; Ojha, Shuchi ; Ning, Shuai ; ... - Advanced Electronic Materials

Abstract A strain‐driven BiFeO ₃ (BFO) tetragonal to rhombohedral phase transition is demonstrated in self‐assembled BiFeO ₃ ‐CoFe ₂ O ₄ (BFO‐CFO) nanocomposites on LaAlO ₃ (110)‐oriented substrates with varying thickness. The CFO forms parallel nanoscale fin‐shaped structures within a BFO matrix. Out‐of‐plane lattice strain from the BFO/CFO interfaces stabilizes the BFO rhombohedral‐like phase. The BFO exhibits a range of ferroelectric textures including stripe domains and centered domain arrangements, and the magnetic anisotropy of CFO shows a thickness‐dependent reorientation.

Strain relaxation and enhanced perpendicular magnetic anisotropy in BiFeO{sub 3}:CoFe{sub 2}O{sub 4} vertically aligned nanocomposite thin films

Journal Article Zhang, Wenrui ; Jiao, Liang ; Li, Leigang ; ... - Applied Physics Letters

Self-assembled BiFeO{sub 3}:CoFe{sub 2}O{sub 4} (BFO:CFO) vertically aligned nanocomposite thin films have been fabricated on SrTiO{sub 3} (001) substrates using pulsed laser deposition. The strain relaxation mechanism between BFO and CFO with a large lattice mismatch has been studied by X-ray diffraction and transmission electron microscopy. The as-prepared nanocomposite films exhibit enhanced perpendicular magnetic anisotropy as the BFO composition increases. Different anisotropy sources have been investigated, suggesting that spin-flop coupling between antiferromagnetic BFO and ferrimagnetic CFO plays a dominant role in enhancing the uniaxial magnetic anisotropy.

Multiferroic and magnetoelectric properties of CoFe{sub 2}O{sub 4}/Pb{sub 1−x}Sr{sub x}TiO{sub 3} composite films

Journal Article Negi, N. S., E-mail: nainjeet12@gmail.com ; Bala, Kanchan ; Yadav, Akash ; ... - Journal of Applied Physics

To realize multiferroic and magnetoelectric properties, bi-layered nanocomposite films consisting of CoFe{sub 2}O{sub 4} (CFO)/Pb{sub 1−x}Sr{sub x}TiO{sub 3} (PST) phases (x = 0.1, 0.2, and 0.3) have been deposited on Pt/TiO{sub 2}/SiO{sub 2}/Si substrate by using a metallo-organic decomposition process. Both the PST perovskite and the CFO spinel phases are confirmed from X-ray diffraction patterns and Raman spectra of the composite films. The composite films exhibit room temperature multiferroic properties. The values of saturation magnetization (M{sub s}), remanent magnetization (M{sub r}), and coercive field (H{sub c}) of the composite films are in the range of 108–119 kA/m, 42–51 kA/m, and 44.5–64.1 kA/m, respectively.

Multiferroics properties in BiFeO{sub 3}/CoFe{sub 2}O{sub 4} heterostructures thin films deposited on (111) SrTiO{sub 3}

Journal Article Singh, Gulab ; Singh, Manoj K., E-mail: gulabau08@gmail.com, E-mail: mksingh100@yahoo.com ; Kumar, Aditya ; ... - AIP Conference Proceedings

The multiferroic properties of BiFeO{sub 3}-CoFe{sub 2}O{sub 4} (BFO-CFO) heterostructures thin film grown on (111) SrTiO{sub 3} (STO) substrates by employing pulsed laser deposition (PLD) method, have been studied.X ray diffraction analysis reveals the presence of BFO and CFO in two separate phases. The heterostructures BFO/CFO/STO(111) thin films show well – shaped hysteresis loop with saturated magnetization and coercive field, which are much larger than pure BFO/STO thin film. The frequency dependent dielectric anomalies in BFO-CFO multilayer are attributed to the interfacial effect across the presence of CFO as a separate phase embedded in BFO matrix.
