We have investigated the microstructure and compositional distribution of the Y1Ba2Cu3O7−x superconductor with scanning electron microscopy, energy dispersive X-ray spectrometry and X-ray diffraction. It has been found that the microregion compositions are far from the ideal composition. This is ...

In this study, it was shown that steady state response in a polycrystalline bulk sample of Y1Ba2Cu3O7−x (YBCO) to a driving current could be dramatically changed by increasing the magnitude of the driving current or reducing it to a finite value or interrupting it completely. The dynamic...

In-plane electric conductivity of Y 1−x Er x Ba 2 Cu 3 O 7−δ single crystals with Er content x ranging from 0 to 0.48 have been measured as a function of temperature from 85 K to 300 K. The temperature dependencies of reduced resistance for all sample are identical suggesting th...
Fig. 1 shows the electrical resistivity under DC magnetic fields from 0 to 1 T in Y1−xNixBa2Cu3O7−δsamples with x = 0.000, 0.002, 0.004. All samples show a sharp transition in zero magnetic field. Sharp transition indicates that the preparation and synthesis of samples were do...
Positron lifetime and Doppler broadened annihilation radiation lineshape measurements have been carried out in Y1Ba2Cu3O7−x as a function of temperature in the range of 300 K to 58 K. The positron lifetime and the peak parameter of the annihilation radiation lineshape are observed to decrease...
The photoresponse of the high Tc superconducting Y1Ba2Cu3O7−x thin film for 0.63 μm and 1.3 μm radiation was measured as a function of temperature and current. We found that current-voltage characteristics are consistent with the vortex-antivortex unbinding transition. The photoresponse whic...
A large number of tunneling measurements on ceramic monophasic Y1Ba2Cu3O7−x samples with different oxygen content using the point-contact geometry was performed. After a deconvolution procedure for removing the thermal broadening, experimental data were analyzed by means of a model of the total ...
