Abstract
Nanosize MgO and TiO2 particles were added to the Bi2Sr2CaCu2Ox, powde r with 20% molar fraction. Powder-in-tube Ag-sheathed tapes were made from the doped powders and heat treated by partial melting processing, Heat treatment optimization was carried out to increase the critical current density, Scanning electron microscopy and energy-dispersive Xr ay spectra were used to study the phases present in the tapes, The eff ect of MgO additions on the flux pinning behavior was investigated by magnetic hysteresis and transport critical current measurements at var ious temperatures and fields.
