The first-order vortex phase transition (FOT) in Bi_2_Sr_2_CaCu_2_O_y_ single crystals with different carrier concentrations was investigated by measuring the in-plane resistivity (r_ab_) under magnetic field applied parallel to the crystallographic c-axis direction. With decreasing the temperature, r_ab_ dropped sharply at the FOT temperature when the applied field was smaller than the second-peak-field (H_pk_) that was determined by measuring the magnetic hysteresis curves at 25-30 K, while no such an abrupt change was observed when the applied field was larger than H_pk_. The temperature range where the FOT was observed was approximately between 0.6 to 0.95 in the scale of the reduced temperature (t=T/T_c_) for all crystals. The first-order transition field (H_t_) as a function of t shifted to higher fields as the carrier concentration of the crystal increased, which can be well scaled by the electromagnetic anisotropy factor (g). Irrespective of the carrier doping level, the temperature dependence of H_t_ is experimentally expressed better by H_t_=a(t^-1^-t), rather than the functional form proposed by the conventional decoupling theory of vortex lattice (H_t_=a(t^-1^-1)). This experimental formula can be accounted for by the decoupling theory if the temperature dependence of the magnetic penetration depth is assumed to scale as l^-2^=a(1-t^2^).

The chemical solution deposition (CSD) technique has been applied to prepare both YBa_2_Cu_3_O_7-d_ (YBCO) and buffer layers on a YSZ substrate. Y_2_O_3_ and CeO_2_ were employed as the buffer layers, and it was confirmed that they grew epitaxially by the CSD method. Cross-sectional TEM observations revealed that Y_2_O_3_ grew up to the top of the film. Furthermore, the YBCO film on the Y_2_O_3_ or CeO_2_/Y_2_O_3_ layers were c-axis aligned and showed a good in-plane alignment. The transition temperature and the critical current density of the YBCO/Y_2_O_3_/YSZ multilayer were 89 K and 4.0x10^4^ A/cm^2^ at 77 K, 0T, respectively.

The amount of magnetic flux that a melt-processed bulk-superconductor can trap has drastically increased recently by the successful synthesis of single domain RE-Ba-Cu-O (RE=Sm, Nd) samples with the addition of Ag. As a result of this progress in processing, it became increasingly important to develop an efficient and practical magnetization technique to extract the potential of the material in applications that use melt-grown superconductors as quasi-permanent magnets. We review our recent works on the melt-growth technique as well as the pulse field magnetization studies. Using these techniques, we have constructed a magnetic field generator, the performance of which is evaluated in this study.

We report on the effect of the atmosphere during the decomposition of the precursors of Sm-Ba-Cu-O bulk superconductors. It was found that the formation of voids was greatly suppressed by two methods, melting in an oxygen gas atmosphere or in vacuum. For both meth-ods, the atmosphere during crystallization was switched to an Ar-gas flowing one. The samples prepared by these methods exhibited high superconducting transition temperatures with sharp transition widths. However, the zero-field critical current density was lower than that of the reference sample, which was prepared by decomposing the precursor in an Ar-gas flowing atmosphere.

We studied the dynamical motion of flux lines in a melt-processed Sm-Ba-Cu-O bulk-superconductor driven by a magnetic pulse using seven small Hall sensors. The time dependence of the magnetic flux density was measured on a crystalline facet line and on an inter-facet region. It was observed that flux lines move faster along the inter-facet region, and a larger amount of magnetic flux is trapped in the facet regions after the application of a magnetic pulse. A comparatively larger pinning effect in the facet region is considered to be responsible for these observations.

We have grown PrBa_2_(Cu_1-x_Zn_x_)_4_O_8_ single crystals with nominal compositions of x=0, 0.05, 0.10, and 0.15, and measured the resistivity along a- and b-axis directions. For the Zn-free sample, the conduction along the b-axis direction was highly metallic, which persisted up to the x=0.15 sample although the doping of Zn increased the resistivity. On the other hand, the a-axis resistivity of the Zn-free crystal exhibited a peak around 130 K, which is attributable to a switching of the dominant conduction path from the Cu-O chain site at low temperature to the CuO_2_ plane at high temperature. With Zn doping, the peak moves to lower temperature and the resistivity extrapolated to T=0 increases, indicating that Zn doping suppresses the coherent conduction across Cu-O chains.

The microstructures of melt-processed NdBCO/Ag samples were investigated. A rather homogeneous distribution of Nd422 particles was found, which can be attributed to the fast growing speed of NdBCO and the large size of Nd422 particles. The dispersion of Ag depended on the content of Ag_2_O, and the phase relation of the NdBCO/Ag system is discussed. We also studied the pulsed field magnetization technique, and found that the amount of magnetic fluxes trapped by SmBCO significantly increased by sandwiching the sample with ferromagnetic yokes and repeatedly applying magnetic pulses with decreasing the amplitude.
