Hysteresis 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 کاملInterface instability in the bulk processing of 2223 BSCCO powders
Interface instability (or s̀ausaging’) has been a major problem in the oxide powder-in-tube tape-rolling process. The fast Fourier transform of core instabilities are ® rst performed to study the rolled tapes and to obtain quantitative information on the wavelengths and magnitudes of the nonuniform pro® les. The existing experimental observations are also re-examined and summarized. Treating thi...
متن کاملEffect 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 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 کاملمطالعه مواد ابررسانای نوع BSCCO(2223) با استفاده از TEM
The EDT A gel processing route has been used to produce (2223) BSCCO superconductiong oxides. Gel - processed (2223) BSCCO material was sintered in air or oxygen to produce specimens for transition temperature determination; the same specimens were characterised by high re.'ioultion transmission electron microscopy fitted with EDAX analysis to yield information about homogeneity, microst...
