We have studied the effect of the pelletization pressure on microstructural and electrical transport properties of superconducting ceramics with starting composition given by the formula $$\text {Bi}_{1.65}\text {Pb}_{0.35}\text {Sr}_2\text {Ca}_{2.5

We have observed a change in the behaviour of voltage-relaxation curves with remnant magnetic flux, when the maximum magnetic field applied before starting the relaxation process, $$H_{am}$$, reaches 80 Oe in two samples of $$\hbox {Bi}_{1.65}\hbox {

In this paper we present a new method to determine separately inter and intragranular magnitudes of polycrystalline superconducting materials, such as: intrinsic effective anisotropy, $$t=\rho _c/\rho _{ab}$$ , the slope of the linear part in the tem

Based on transport measurements performed on Bi-2223 polycrystalline superconductors, we have determined the in-plane resistivity, $$\rho _{ab}(T)$$ , the effective grain resistivity, $$\rho _g(T)$$ , and the effective intergranular resistivity, $$\r
