By varying the content ratio of the initial products, nine compounds of the Y-Ba-Cu-0 system have been produced. These were studied to find their T, values, critical currents j , at 77 K and effects of compression stress on the U(j)-curves. Mechanical loading has been found to result in a shift of t
The effect of Tl substitution for Hg in the Hg-Ba-Cu-O system has been investigated for a wide substitution range. A single-layer system was maintained until 50% of Tl substitution, and above 50%, a double-layer system was observed. Tl substitution brought about an overdoping state in the CuO 2 plan
In this investigation resonance interaction between superconductors and radio frequency field has been studied by a modified electron spin resonance equipment. At transition temperature (T c ) the amplitude of the response increased about 20-25 times and the resonance frequency of the circuit from 1
The transition temperature of \(\mathrm{YBa}_{2} \mathrm{Cu}_{4} \mathrm{O}_{8}(124)\) is increased by about \(10 \mathrm{~K}\) by doping with calcium, whereas Ca substitution in \(\mathrm{Y}_{2} \mathrm{Ba}_{4} \mathrm{Cu}_{7} \mathrm{O}_{14+x}\) (247) has no effect on \(T_{\mathrm{c}}\).

Shock-synthesis experiments of REBa 2 Cu 3 O y (RE ؍ Y, Eu, and La) were carried out for the mixture of component oxides as starting materials using a 25 mm-bore propellant gun. Both tetragonal EuBa 2 Cu 3 O y with c/a ؍ 3.00 and cubic LaBa 2 Cu 3 O y were successfully synthesized by shock compr
