Effect of various mechanical deformation techniques on pinning force densities in Ag / Bi-2223 tapes

Abstract

Ag/Bi-2223 tapes were fabricated using the Powder-In-Tube method, involyH1~ intermediate deformation techniques of sandwich rolling (SR), pressing (P) and nQl1l1~~ rolling (NR). Magnetic field B depen:lence of Jc was measured. Depending 6rt:~~' relationship between )c and B, the irreversible magnetic field Birr was determineli)lIl..W: pinning force density… (More)
