✦ Synopsis

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 (at room temperature) to 3.5 MHz. The amplitude of the response increases only in the transition region. The frequency versus temperature curve is much alike the resistance versus temperature curve, i.e. the frequency and the resistance first slowly, then sharply decrease near T c . At temperatures below T c (80 K) the frequency approaches a saturation while the resonance interaction features a magnetic memory effect.

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

This paper presents Monte Carlo simulations of the positron diffusion process in a solid grain when an external magnetic field is applied. Our work has focused on the fraction of positrons, which reach the grain boundary because such a parameter can be observed in positron experiments. The simulatio
