Аннотация: Y0.75Nd0.25Ba2Cu3O7−d superconductor has the peak effect with pronounced fishtail feature on magnetization hysteresis. The magnetic field of the peak effect maximum is in ~4 times higher than one of NdBa2Cu3O7−d. The magnetization hysteresis is tilted anticlockwise due to paramagnetic Nd3+ ions occurred on the surface of grains and in the vortex cores.

Аннотация: The kinetics of ordering in nanostructured CoPt particles is investigated. The low activation energy (58 ± 2 kJ/mol) of the ordering process indicates that the kinetics of ordering is not limited by bulk diffusion. Coercivity grows along with the degree of ordering and reaches its maximum value of 14.2 kOe upon the complete ordering of CoPt alloy with a crystallite size of no more than that of a single domain. © 2017, Allerton Press, Inc.

Аннотация: Polycrystalline Y1−xNdxBa2Cu3O7−δ (x=0.02, 0.11, and 0.25) superconductors are synthesized. Nd atoms are uniformly distributed over grains. The magnetization loops of the samples have a pronounced second peak in a wide temperature range. The magnetization data are analyzed using the extended critical state model. It is found that the order-disorder transition of the vortex lattice is affected by doping with neodymium and temperature; the second-peak field and width decrease monotonically with increasing x value. The undoped polycrystalline YBa2Cu3O7−δ compound is assumed to exhibit the peak effect in higher magnetic fields.

Аннотация: We have studied the magnetoresistive effect in bulk 1-2-3 YBCO + CuO and 1-2-3 YBCO + BaPb1-xSnxO3 composites prepared using the fast backing technique. We have found that the composites exhibit large magnetoresistance in low magnetic fields (< 100 Oe) for a broad temperature range. We have studied the experimental dependences of resistivity versus magnetic field at various transport current densities. The high-T-C superconductor (HTSC) based composites exhibit a much higher sensitivity to weak magnetic fields at liquid nitrogen temperature, compared to that for pure HTSC ceramics. This effect is attractive for practical applications and the composite materials can be used as active elements in magnetic field sensor devices.

Аннотация: Bulk Y3/4Lu1/4Ba2Cu3O7 + BaPb1-xFexO3 composites representing a model of a network of superconductor-normal metal-superconductor (SNS) Josephson junctions with paramagnetic impurities (Fe) in the N layers have been prepared. The transport properties of the composites have been studied. An exponential decay of the critical current with increasing Fe content in the non-superconducting ingredient of the composite has been observed. Such a behaviour is accounted for in terms of the de Gennes proximity effect theory.

Аннотация: The hysteretic behavior of critical current j(C)(H) and magneto-resistance R(H) of composites Y-Ba-Cu-O + CuO have been studied and presented. The composites represent the network of tunnel-type Josephson junctions where copper oxide acts as a material forming barriers between superconducting (YBCO) crystallites. The characteristic features of R(H) and j(C)(H) dependences are discussed in the frames of the conception of "two level superconducting system" (the Josephson media and HTSC crystallites) which is realized in the composites under study.

Аннотация: The magnetoresistive properties of bulk YBCO + CuO and YBCO + BaPb0.75Sn0.25O3 composites for different orientations of external magnetic field H and macroscopic transport current j have been measured. These composites exhibit large magnetoresistance in weak magnetic fields (< 100 Oe), which makes them promising candidates for practical application in magnetic field sensor devices. The difference between.( T) dependences, magnetoresistance curves R( H) and current - voltage characteristics measured for H parallel to j and H || j is observed indicating the presence of the Lorentz- force- dependent dissipation in the composites. Angular dependences of magnetoresistance R(theta) ( where theta = angle H, j) of the composites in weak magnetic fields are found to be proportional to sin(2)theta. This fact suggests that the flux flow in the intergrain boundaries is responsible for the large magnetoresistive effect observed in the composites.

Аннотация: The experimental results of the effect of the magnetic field (up to 60 kOe) on the broadening of the resistive transition of bulk composites Y3/4Lu1/4Ba2CU3O7 (YBCO) + CuO are presented. These composites represent the network of the tunnel-type Josephson junctions where the copper oxide acts as a material forming barriers between YBCO crystallites. The mechanisms responsible for broadening of the resistive transition under magnetic field are discussed. The analysis of experimental R(7) dependences have shown that in the low field range 0-10(2) Oe, the R(7) dependences are described well by the Ambegaokar-Halperin (AH) model. In the range 10(3)-6 x 10(4) Oe, the dissipation follows Arrhenius law R similar to exp(-U(H)/k(B)T) characteristic for thermally activated flux creep model. In the range H similar to 10(2)-10(3), the crossover from AH to flux creep dissipation mechanisms occurs. (c) 2006 Elsevier B.V. All rights reserved.

Аннотация: The temperature dependence of resistivity and the bulk modulus are calculated on the Kondo lattice, with ring exchange between localized spins, using the spin-polaron and adiabatic approximation. Peak and zero values of the bulk modulus as functions of temperature and concentration are determined below the temperature of the transition to the paramagnetic state. The effects of the nearest order between transverse spin components and a value of the ring exchange between localized spins on magnetoresistivity are estimated.

Аннотация: Flux-Pinning Docking Interfaces (FPDI) in satellite systems were developed using bulk superconductors and permanent magnets in previous works. However, such FPDIs have limited magnetic field strength, consist of heavy-weight material, and can only be used with a single purpose, i.e., as chasing or docking satellite. Replacing the magnetic material in the FPDI by a trapped field (TF)-magnet would enable the interface to operate for both purposes, i.e., generating a (stronger) magnetic field and trapping it. We show the requirements for such a system and discuss the possible gains when using a TF-FPDI in satellites. To reduce the system weight, the use of superconducting foams as superconducting material is discussed in detail. Furthermore, the use of superconducting foams, the size of which can be easily upscaled, may also comprise the function of the damping material, so even more weight could be saved for the payload.

Magnetic ion substitution and peak effect in YBCO: the strange case of Y1–xGd xBa2Cu3O7–δ / D. M. Gokhfeld, S. V. Semenov, I. V. Nemtsev [et al.] // J. Supercond.

Кл.слова (ненормированные):
Peak effect -- Bulk superconductors -- Critical current -- Pinning -- X-ray diffraction -- YBCO -- Doping -- Paramagnetic magnetization
Аннотация: We present the results of a study of the superconducting and paramagnetic properties of polycrystalline Y1–xGdxBa2Cu3O7–δ samples. The critical current density and critical temperature of YBCO were weakly decreased by the Gd doping. A peak effect, which is a nonmonotonic dependence of the critical current density on magnetic field, was detected for all samples. The peak position shifted to higher magnetic fields with increasing Gd content. This behavior is opposite to the shift of the peak effect observed for other YBCO compounds doped by magnetic ions. This unusual behavior is apparently related to the realized granular structure instead of the type of doping ion. A correlation between the peak position and the granule size was found in the investigated samples and other polycrystalline YBCO compounds.

Trapped flux -- Vortex pinning -- Monte Carlo -- Trapped field magnet -- HTS foam
Аннотация: The Monte Carlo method has been used to calculate the trapped magnetic field in superconducting plates with holes. The mechanism of flux pinning on the holes is implemented with special subprocesses added to the algorithm: vortex capture and emission, both occurring on the hole boundaries. Secondary peaks related to the holes emerge on the calculated profiles of the trapped magnetic field. It has been found that these peaks disappear in plates with sufficiently strong pinning or when the computational mesh is coarse (the case corresponding to a low resolution of probes in experiments). The dependence of the trapped field on the hole radius has been analyzed.
