Abstract

Magnetoresistance and radio frequency penetration depth techniques are used to study grain connectivity and broadening of superconducting transition. We study and compare these issues in clean polycrytalline samples of three different superconducting systems e.g. MgB2, NbSe2 and Bi2Sr2Ca2Cu3O10. From the rf response, the bulk pinning force constant is evaluated. From high field transport measurements, H-T phase diagram is ascertained for the three systems with varying degrees of fluctuation and connectivity.
