Fig. 2 Long range magnetic order: incommensurate spin cycloid. The arrows correspond to the antiferromagnetic vector L that changes its orientation in space θ=θ(x). The position of satellite peaks observed in time-of-flight neutron studies along the [110]hex (see Fig.3a) enabled determination of the period of the spin cycloid to be o ~. 620A.

Multiferroic Consequence of Porous (BiFeO3) x -(BiCrO3)1−x Composite.

Recent electron spin resonance in-vestigations have also shown an induced phase transition from cycloidal to homogeneous antiferromagnetic spin or-ders for H.18 T. 17. This induced phase transition can be understood by the following Landau-Ginzburg sLGd theory: 14-18. F. homogeneous, F. cycloid, s1ad F. cycloid =− 1 4A sg·P. z. d. 2 + K. 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.

Revisiting spin cycloids in multiferroic BiFeO 3.

BiFe1−x Zn x O3 thin films (x=0, 0.05, 0.1, 0.2, and 0.3) were prepared on LaNiO3 buffered surface oxidized Si substrates using pulsed laser deposition. The effect of Zn dopants on the structural, electrical, magnetic properties, and exchange bias on NiFe layers for BiFeO3 thin films has been systematically investigated. X ray diffraction and Raman spectra show that BiFe1−x Zn x O3 thin. Bismuth ferrite (BiFeO 3) has recently become interesting as a room-temperature multiferroic material, and a variety of prototype devices have been designed based on its thin films.A low-cost and simple processing technique for large-area and high-quality BiFeO 3 thin films that is compatible with current semiconductor technologies is therefore urgently needed. In BiFeO3, a well-known room-temperature multiferroic, competition between various exchange interactions gives rise to non-collinear spin order, manifesting as an incommensurate spin cycloid with period of 64 nm. We report on the stability and scaling behaviour of the cycloid in (110)-oriented epitaxial Co-doped BiFeO3 thin films.

Chapter V. Nanostructured multiferroic system BiFeO3... The linear magnetoelectric effect is suppressed by the presence of the spin cycloid, thus it would be expected to macroscopically observe higher order... Thin films form on the substrate through a process entailing nucleation and growth. During nucleation, growth centres (nuclei) appear.

Multiferroic Bi0.8La0.2FeO3 （BLFO） epitaxial films were deposited directly on SrTiO3 （001） substrates through magnetron sputtering. Using Fe as ferromagnetic layer,both the exchange bias and coercivity of Fe/BLFO bilayers along the in-plane with different thickness of Fe layer were investigated.

SciEntific REPORtS | (2018) 8:405 DOI1.13s1-1-13-1 Spin-coupling-induced Improper Polarizations and Latent Magnetization in Multiferroic BiFeO3 Hyun Myung Jang 1, Hyeon Han 1 & Jung-Hoon Lee2 Multiferroic BiFeO 3 (BFO) that exhibits a gigantic o-centering polarization (OCP) is the most extensively studied material among all multiferroics. 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 BiFeO3 (BFO). Although at room temperature, bulk BFO is ferroelectric (2) and anti-ferromagnetic (3-5), Wang et al. (1) reported that a 70-nm film shows both an enhanced ferroelectric polarization (90 μC cm-2) and a. Understanding and manipulating complex spin texture in multiferroics can offer new perspectives for electric field-controlled spin manipulation. In BiFeO3, 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 64 nm.
