Abstract

HAL is a multidisciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.

Magnetoelectric coupling in CoFe2O4‐Pb(Zr0.2Ti0.8)O3 coaxial nanofibers

“…One may also note that both the amplitude butterfly curve and the phase hysteresis loop exhibit asymmetrical characteristics with a remarkable shift along the applied bias voltage axis, which is usually considered to be a clear indication of the imprint effect. This effect was frequently observed in ferroelectric thin films, 19,20 nanocomposites, 10,21 nanowires 22,23 as well as core‐shell NFs 2,24 . The imprint effect in ferroelectrics may originate from various factors, such as a built‐in electric field, 19,20 a contact barrier between the ferroelectric film and the metal electrode, 25 and the domain wall pinning, 22 though the origin is still under discussion.…”

Piezoelectric Properties of Pb1−xLax(Zr0.52Ti0.48)1−x/4O3 Thin Films Studied by In Situ X-ray Diffraction

“…in situ X-ray diffraction experiments were performed at the DiffAbs beamline at SOLEIL synchrotron (St Aubin, France) [23,24]. The incident monochromatic 10 keV X-ray beam was collimated to a size of 50 µm using a pinhole placed about 20 cm upstream of the sample.…”

“…Static and alternating electric fields were applied, employing an Analog Output card (model PXI 3U from ADLINK) that allows for the generation of a bipolar tension in the range of ±10 V (5 mA maximum current). For AC measurements of the piezoelectric hysteresis loops, the X-ray diffraction signal was acquired by accumulating (internally) several thousand images, each of them with very short exposure (typically 1 µs) and synchronously taken at the very same voltage during the AC cycle [24]. Once the counting statistics were sufficient, the synchronization was shifted to the next voltage point in order to describe the hysteresis loop.…”

A critical review: the impact of electrical poling on the longitudinal piezoelectric strain coefficient

“…Cornelius et al explained the polarization response of the P – E hysteresis loop, and the S – E butterfly loop of self-poled PZT thin films deposited on Pt/TiO 2 /SiO 2 /Si substrates. 47 d 33 was obtained from the butterfly curves as shown in Fig. 3(B).…”
