We investigated the superconducting transition and the pinning properties ofundoped and Ag-doped FeSe0.94 at magnetic fields up to 14 T. It was establishedthat due to Ag addition the hexagonal phase formation in melted FeSe0.94samples is suppressed and the grain connectivity is strongly improved. Theobtained superconducting zero-field transition becomes sharp (with a transitionwidth below 1 K), Tc and the upper critical field were found to increase,whereas the normal state resistivity significantly reduces becoming comparablewith those of FeSe single crystals. In addition, a considerablemagnetoresistance was observed due to Ag doping. The resistive transition ofundoped and Ag-doped FeSe0.94 is dominated by thermally activated flux flow.From the activation energy U vs H dependence, a crossover from single-vortexpinning to a collective creep pinning behavior was found with increasing themagnetic field.
