Title: Ultrafast relaxation dynamics in BiFeO₃/YBa₂Cu₃O₇ bilayers

Abstract

The temperature dependence of the relaxation dynamics in the bilayer thin film heterostructure composed of multiferroic BiFeO₃ (BFO) and superconducting YBa₂Cu₃O₇ (YBCO) grown on (001) SrTiO₃ substrate is studied by time-resolved pump-probe technique, and compared with that of pure YBCO thin film grown under the same growth conditions. The superconductivity of YBCO is found to be retained in the heterostructure. We observe a speeding up of the YBCO recombination dynamics in the superconducting state of the heterostructure, and attribute it to the presence of weak ferromagnetism at the BFO/YBCOinterface as observed inmagnetization data. An extension of the Rothwarf-Taylor model is used to fit the ultrafast dynamics of BFO/YBCO, that models an increased quasiparticle occupation of the ferromagnetic interfacial layer in the superconducting state of YBCO.

Direct observation of temperature dependent magnetic domain structure of the multiferroic La{sub 0.66}Sr{sub 0.34}MnO{sub 3}/BiFeO{sub 3} bilayer system by x-ray linear dichroism- and x-ray magnetic circular dichroism-photoemission electron microscopy

Low-thickness La{sub 0.66}Sr{sub 0.34}MnO{sub 3} (LSMO)/BiFeO{sub 3} (BFO) thin film samples deposited on SrTiO{sub 3} were imaged by high resolution x-ray microscopy at different temperatures. The ultra-thin thickness of the top layer allows to image both the ferromagnetic domain structure of LSMO and the multiferroic domain structure of the buried BFO layer, opening a path to a direct observation of coupling at the interface on a microscopic level. By comparing the domain size and structure of the BFO and LSMO, we observed that, in contrast to LSMO single layers, LSMO/BFO multilayers show a strong temperature dependence of the ferromagnetic domainmore »« less

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; Kumar, Aditya; Dussan, S.; ... - 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.

Multiferroic behavior and impedance spectroscopy of bilayered BiFeO{sub 3}/CoFe{sub 2}O{sub 4} thin films

Journal Article Jiagang, Wu; Wang, John - Journal of Applied Physics

Lead-free bilayered multiferroic thin films consisting of BiFeO{sub 3} (BFO) and CoFe{sub 2}O{sub 4} (CFO) layers with different thicknesses were grown on SrRuO{sub 3}-coated Pt/TiO{sub 2}/SiO{sub 2}/Si substrates by radio frequency sputtering. The effects of constituent layer thicknesses on the ferroelectric and magnetic behavior have been studied. The physical behaviors are shown to strongly depend on the thicknesses of the constituent layers. BFO (220 nm)/CFO (30 nm) bilayered thin film demonstrated much improved ferroelectric and ferromagnetic behavior (2P{sub r}=144.2 muC/cm{sup 2}, 2E{sub c}=778.0 kV/cm, M{sub s}=61.2 emu/cm{sup 3}, and H{sub c}=200.8 Oe) as compared to those of the single layermore »« less

Journal Article Ichinose, T.; Begum, H.; Sato, S.; ... - AIP Advances

BiFeO{sub 3} (BFO) and La{sub x}Sr{sub y}Mn{sub z}O{sub 3} (LSMO) films were epitaxially grown on SrTiO{sub 3} (100) substrates by r.f. magnetron sputtering with various oxygen gas flow ratios (F{sub O2}). Compositional ratios of each atom in both of BFO and LSMO could be controlled kept to around 10 at.% by changing F{sub O2}.

Conductance control at the LaAlO{sub 3}/SrTiO{sub 3}-interface by a multiferroic BiFeO{sub 3} ad-layer

Journal Article Mix, Christian; Finizio, Simone; Kläui, Mathias; ... - Applied Physics Letters

Multilayered BiFeO{sub 3} (BFO)/LaAlO{sub 3} (LAO) thin film samples were fabricated on SrTiO{sub 3} (STO) substrates by pulsed laser deposition. In this work, the ferroelectric polarization of a multiferroic BFO ad-layer on top of the quasi-two-dimensional electron gas (2DEG) at the LAO/STO interface is used to manipulate the conductivity of the quasi-2DEG. By microstructuring the conductive area of the LAO/STO-interface, a four-point geometry for the measurement of the resistivity was achieved. Piezo force microscopy allows for imaging and poling the spontaneous ferroelectric polarization of the multiferroic layer. The resistance changes showed a linear dependence on the area scanned and amore »« less
