“…Building appropriate artificial flux-pinning centers in the coated conductor can significantly improve its current carrying capacity. The methods of manually introducing the pinning centers mainly include substrate surface modification [1,2], the introduction of an impurity phase [3,4], rare-earth doping [5][6][7] and particle irradiation [8,9]. At our group, Ta ion irradiation and doping with five mixed elements were applied to YBCO-coated conductors to produce columnar defects with the size of 7-9 nm in the films [10], forming effective pinning centers with enhanced flux-pinning properties.…”

YBa2Cu3O7−δ (YBCO) thin films with the addition of Cl were prepared on Hastelloy tape by the extremely low fluorine metal-organic deposition (MOD) technique. The composition and microstructure of the present samples were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). It was revealed that the Cl-added YBCO thin films achieved better texture and density compared with the pure YBCO films. The superconducting properties at magnetic fields were measured using the magnetic property measurement system (MPMS). The results showed that the sample onset transition temperature (Tc, on) did not change significantly after the addition of Cl. The critical current density (Jc) in the presence of YBCO with the addition of Cl increased significantly. Meanwhile, both the Jc and gravitational force (Fp) of the (Cl, Hf) co-added YBCO films were further enhanced at different magnetic fields. The thermodynamic analysis of the BaCO3 removal reaction revealed that the addition of Cl to YBCO formed chlorine compounds, which were effective in avoiding the formation of BaCO3. Further, the calculation results of the Gibbs free energy at different pressure quotients showed that the stability of the relevant chlorine compounds occurred in the order of BaCl2 > CuCl2 > YCl3 and the oxidation of BaCl2 to BaO required a higher temperature compared to BaF2, implying the potential advantages of inhibiting the a-axis growth.

“…[11][12][13] The SHI irradiations have been used to alter the property of many oxide materials including high T c superconductors, colossal magneto resistance (CMR) oxides, and many transition metal oxides owing to their ability of tailor materials properties via controlled introduction of defects in materials by selecting appropriate ion type and energy. [14][15][16][17][18][19][20][21][22] There are reports in the literature where effect of irradiations on the structural, magnetic and electronic properties of LNO have been studied. [23][24][25] Kumar Raman spectroscopy being sensitive to structural distortions and strain, has been used to probe ion irradiation induced defects and their impact on phononic properties of oxide systems.…”

The effects of Ag15+ (200 MeV) swift heavy ion irradiations on the structural and phononic properties of epitaxial LaNiO3 (LNO) thin film have been investigated using high resolution x-ray diffraction and Raman spectroscopy. After irradiation, the decrease in the out-of-plane lattice parameter of LNO toward its bulk value indicates the relaxation of epitaxial strain. The temperature dependency of phononic response for different ion irradiation doses was studied by performing the Raman measurements in a temperature range of 80−300 K. For pristine as well as irradiated samples of LNO, the observed phononic modes A1g and Eg shows softening with an increment in the temperature. The temperature coefficient of both modes varies with ion fluence. For the A1g mode, temperature coefficient increases from −0.087 cm−1 K−1 for pristine to −0.092 cm−1 K−1 for a maximum ion fluence of 1012 ions/cm2, while for the Eg mode, it decreases from −0.022 cm−1 K−1 for pristine to −0.015 cm−1 K−1 for 1012 ions/cm2. Raman frequency shift for both the modes shows non-linear behavior with temperature. This temperature dependent behavior was quantitatively analyzed by using a model which suggests that Raman shifts of the A1g mode emerged predominantly due to four phonon processes whereas, for the Eg mode, major contribution came from the thermal expansion effect. Ion irradiation did not change the dominating mechanism resulting in these temperature dependent Raman shifts, although the relative contribution of different processes was altered with ion fluence.

“…The SHI-irradiated polymers have been used to fabricate the ion track membrane after chemical etching, , and the pore diameters range from 10 nm to tens of micrometers. The ion track in many crystalline materials is amorphous, and its geometry is usually cylindrical. − However, recent experimental results show that the ion track in rutile TiO 2 , MoS 2 , and CeO 2 is not amorphous but still crystalline with many nanovoids inside. − More interestingly, the track geometry in these materials is highly related to the ion path length or sample thickness. These results have proved that the outflow of the thermal spike-induced molten material and epitaxial recrystallization play an important role in track formation.…”

Extending the fabrication methodology of solid-state nanopores in a wide range of materials is significant in the fields of single molecule detection, nanofluidic devices, and nanofiltration membranes. Here, we demonstrate a new method to directly fabricate size-and density-controllable sub-10 nm nanopores in WO 3 nanosheets using single swift heavy ions (SHIs) without any chemical etching process. By selecting ions of different electronic energy losses (S e ), nanopores with sizes from 1.8 to 7.4 nm can be created in WO 3 nanosheets. The creation efficiency of nanopores achieves ∼100% for S e > 20 keV/nm, and there exists a critical thickness below which nanopores can be created. Combined with molecular dynamics simulations, we propose that the viscosity and surface tension of the transient molten phase caused by SHIs are the key factors for the formation of nanopores. This method paves a way to fabricate solid-state nanopores in materials with a low viscosity and surface tension.
