Title: Dwell Time Influence on Spark Plasma-Sintered MgB{sub 2}

Abstract

Samples of MgB{sub 2} with relative density above 95% were obtained by spark plasma sintering (SPS) at 1150 °C for a heating time of 100 °C/min and a maximum pressure of 95 MPa. Dwell time was of 1, 4, 7, 10, and 20 min. Samples show that dwell time has a low influence on superconducting characteristics. However, small differences were observed and they are discussed from the viewpoint of density, structural, microstructural, critical current density, irreversibility field, and pinning type. The dominant contribution for all investigated samples is given by point and δT{sub c} pinning.
