“…Secondly, different well-established synthesis techniques have been successfully designed to fabricate polycrystalline and single crystalline samples with large sizes from these oxides. Additionally, the physical properties of these materials could be feasibly tuned by partial or complete atomic substitutions [1][2][3][4][5].…”

“…Yttrium-barium-copper oxide (YBCO) is a widely used high-temperature superconductor, known for being the first superconductor characterized by a critical temperature greater than 77 K. The most important characteristics of YBCO are the critical temperature Tc -the temperature range 80-93 K [1][2][3], the critical induction Bc -5.7 T, and the critical current density J = 7⋅10 6 A /cm 2 . Currently, the attempts are being made to increase the critical temperature of YBCO by doping the system with materials of different composition and concentration [4][5][6][7][8][9][10][11]. The dependence of superconductor properties on such parameters as crystal lattice defects [12][13][14], pressure [15], and radiation exposure [16] is also being studied.…”

The article examines the effect of nickel nanoparticles on the magnetic properties of the YBCO superconductor. The ceramics were obtained by solid-phase synthesis using yttrium oxide, copper (II) oxide, and barium carbonate with the addition of carbon nanotubes "Taunite" of different concentrations (0, 20, 50, 70, 100 mg). Magnetic studies have demonstrated that ferromagnetism and superparamagnetism are both observed in the samples, which can be explained by the presence of nickel particles. The dependences of the magnetization in the applied magnetic field of the sample without the addition of the carbon nanotubes "Taunite" have a paramagnetic course, and their slope monotonically increased with decreasing temperature. The coercive force of the samples and the value of the magnetic moment has been determined to increase upon the decrease in temperature. The high homogeneity of the heterostructures has been demonstrated in the graphs of FC/ZFC explained by the uneven distribution of nickel nanoparticles, which do not integrate into the crystal lattice and, due to the long-range order of interaction, do not make a strong contribution to the magnetization.

“…Besides, such important parameters of the system as the London penetration depth (150-300 nm), the energy gap (20−25 MeV), and the critical magnetic field (250 T) were previously determined [2]. At the moment, it is relevant to study the dependence of the critical temperature on the composition and proportion of alloying materials in YBCO [3][4][5][6], defects, and features of its crystal lattice [7][8][9]. Likewise, the work is also actively underway to develop a universal theory of high-temperature superconductivity, including the basis of the YBCO system [10,11].…”

The article presents a study of the transport properties of high-temperature superconducting compounds of the Y-Ba-Cu-O system with the addition of the carbon nanomaterial (carbon nanotubes) "Taunite" in different concentrations. According to the data of X-ray phase analysis, scanning electron microscopy and magnetic measurements, it was determined that the carbon nanotube "Taunite" contains ferro-and superparamagnetic particles (~ 30 nm). The dependences of the resistance of the samples on the temperature have been constructed, and the temperature of the transition of the samples to the superconducting state (~ 90 K) has been determined, and the features ("stages") on the resistance curves are observed below. Nickel nanoparticles in the carbon nanotubes "Taunite" have been established to not affect the critical temperature of the superconducting transition, yet after reaching a certain concentration, they destroy the superconducting state.
