Effect of various mechanical deformation techniques on pinning force densities in Ag/Bi-2223 tapes
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 F was calculated. The experimental res...
متن کاملHysteresis losses in BSCCO(2223)/Ag multifilamentary tapes
In order to investigate hysteresis losses on Ag-sheathed BSCCO(2223) multifilamentary tapes, we perform hysteresis loop measurements, with the external magnetic field He perpendicular to the tape surface, for different sweep rates of the magnetic field and at different temperatures T. The experimental results show a sweep rate dependence, equivalent to a frequency dependence of the hysteretic l...
متن کاملPreisach-type hysteresis modelling in Bi-2223 tapes
An identiication method for Preisach-type models of hysteresis is presented. By using a phenomenological Preisach-type model for hysteresis we can obtain an exact model for the magnetisation hysteresis in the cases of tapes with strip and with elliptical cross section geometries. With a parametrisation by Maclaurin series, it is possible to identify such a model for any other geometry. An addit...
متن کاملThe Current Distribution in Bi-2223/Ag HTS Conductors: Comparing Hall Probe and Magnetic Knife
We analyzed the current distribution in three Bi-2223/Ag tapes with different filament lay-out, comparing the results of magnetic knife and Hall probe experiments. Detailed knowledge of the current distribution can be useful for the diagnostics of HTS conductors. The lateral current distribution was measured with the non-destructive magnetic knife technique and used to calculate the correspondi...
متن کاملبررسی پذیرفتاری مغناطیسی AC در ابررساناهای حجمی (Bi-Pb)2223
The temperature dependence of ac susceptibility of (Bi-Pb)2223 polycrystalline samples was measured as a function of frequency and ac field amplitude. Analysis of the temperature dependence of the AC susceptibility near the transition temperature (Tc) has been done employing Bean’s critical state model. The observed variation of intergranular critical current densities (Jc) with temperature i...
