A. Benlhachemi et al., INTERFACES AND PRESSURE EFFECTS IN SUPERCONDUCTING BI-2223 BISMUTH CUPRATE GRANULAR-MATERIALS AND BI-2223 POLYMER COMPOSITES, Annales de chimie, 20(6), 1995, pp. 335-344
Granular materials and polymer/Bi-2223 superconductor composites have
been characterized using complex impedance spectroscopy and low temper
ature electrical resistance measurements. Pressure effects are connect
ed with the abnormal electrical properties. The interfaces can be char
acterized using a simple modelling.
