“…We observe only a line which is present as well in the topographic and piezoelectric mode indicating that this line is a defect on the surface. Since we observed neither walls and domains, we conclude that our LiNbO 3 substrates exhibit a single ferroelectric domain configuration 31,32 . Coercive magnetic field versus angle φ between the magnetic field and k SAW direction for the Co layer on Al2O3 (blue squares) and LiNbO3 (red dots).…”

“…To clear this point, we observed the sample (using polarized light microscopy) on a much smaller scale (110 µm × 83 µm) in an attempt to reveal walls between anti-parallel domains. According to V.G.Zalessky et al 31 , domain walls induce optical contrast on this scale. Moreover, piezoelectric force microscopy (PFM) measurement is performed in order to detect micro-and/or nano-metric ferroelectric domains.…”

We present spin pumping experiments in Co/Pt bilayers grown on Al2O3(0001) and on ferroelectric Y-cut LiNbO3 substrates. Spin pumping is triggered by resonant ferromagnetic resonance induced by surface acoustic waves. We observe that spin pumping efficiency varies when both the magnetization vector and the acoustic wave vector are reversed in Pt/Co/LiNbO3. This phenomenon is not observed in Pt/Co/Al2O3. We propose that the in-plane electric polarization of LiNbO3 is at the origin of the observed phenomenon. These observations open up the perspective of an electric field control of spin pumping efficiency.

Domain formation on the nonpolar lithium niobate surfaces under electron-beam irradiation: A review

In this review, our recent results on the electron-beam domain writing (EBDW) on the nonpolar surfaces of LiNbO3 crystals of different compositions are presented. Under EB irradiation of the nonpolar surfaces, domains nucleated in irradiation points grow frontally along the polar [Formula: see text]-direction in a thin (of microns in thickness) surface layer; the driving force is the tangential component of space-charge fields induced by EB in irradiation points. This geometry of the experiment provides a possibility of three-dimensional (3D) characterization of domain patterns using the combination of atomic force microscopy (AFM) and second harmonic generation (SHG) confocal microscopy methods. The obtained results permitted us to relate the main characteristics of domain formation (the domain sizes and velocity [Formula: see text] of the frontal motion) to the irradiation conditions (the accelerating voltage [Formula: see text] of scanning electron microscopy (SEM), EB current [Formula: see text], the inserted charge [Formula: see text]). The domain depth [Formula: see text] is controlled by [Formula: see text] via the electron penetration depth; the domain length [Formula: see text] increases linearly with [Formula: see text] owing to the domain frontal growth by the viscous friction law. The electron emission coefficient [Formula: see text] affects the domain formation due to the fundamental dependence of [Formula: see text] on [Formula: see text]. In the framework of current approach to EB charging of insulators, the effect of an enhanced conductance on EBDW characteristics is analyzed. The difference between EBDW characteristics observed in varied LiNbO3 compositions is discussed in the framework of the intrinsic defect structure of LiNbO3. The obtained results extend the possibility of EBDW application to a wider range of crystals.

“…Despite the first direct optical observation of the forward growth in barium titanate single crystals published in the classical paper of Merz, this process is insufficiently studied because of spatial resolution limitations in the optical microscopy. Furthermore, the local polarization reversal on the nonpolar cuts was studied in LN by local application of electric field using metallic needle, electron beam, , and conductive SPM tip. − …”

The understanding of self-organization processes at the micro- and nanoscale is of fundamental interest and is important to meet the great challenges in further miniaturization of electronic devices to the nanoscale. Here, we report self-organized quasi-regular nanodomain structure formation on the nonpolar cut of a ferroelectric lithium niobate single crystal. These structures were formed along the trajectory of grounded scanning probe microscope tip approaching or moving away from the freshly switched region. Detailed analysis of the formed structures revealed internal organization by the length of the needle-like domains, which ranged from uniform to quasi-periodic and even chaotic modes as a function of distance from the switched region. Comprehensive investigations and numerical simulations allowed to attribute explored phenomena to charge injection during the field application and further switching under the action of electric field induced by injected charges near the tip. Self-organization and quasi-periodicity were explained by the effective screening and long-range electrostatic interaction between the individual needle-like domains.
