Abstract
The effect of the DC transport current (I) on the superconducting and normal properties of ceramic hightemperature superconducting bismuth-based oxides of different compositions was studied by temperature dependent resistivity (r) measurements at fixed points around liquid nitrogen temperature under the presence of Earth's geomagnetic field. It has been shown that the observed results are significantly dependent on the sample preparation and post-processing conditions as well as on the measurement temperature.
