Experiment of enhancing critical current in Bi-2223/Ag tape by means of ferromagnetic shielding
Critical current in multifilamentary Ag-sheath Bi-2223 tape is enhanced to some extent by means of thin and narrow coating of pure nickel. The concept of enhancing critical current is based on the magnetic shielding effect resulting in redirection of self-field flux lines. The Ni coating was introduced at the edge regime of the tape in order to redirect the perpendicular component of self-field...
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 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 کاملStudies on physical properties of nanostructured Zn doped Bi-2223 superconductors
Samples of (Bi,Pb)2Sr2Ca2Cu3-xZnxO10+δ (Bi-2223, x=0.0 to 0.30) were synthesized by solid-state reaction route. We carefully synthesized these compounds and characterized them for phase formation, structural/microstructural, electrical and magnetic measurements. The phase identification /gross structural characteristics of synthesized (HTSC) materials explored through powder x-ray diffractomete...
متن کاملمطالعهی پدیده‌ی فرونشانی و مشخصه‌یابی آن بر روی نوار ابررسانای دمابالا‌ی Bi-2223/Ag
امروزه، کاربرد مگنت‌های ابررسانای دمابالا به دلیل بهبود کیفیت سیم ابررسانا، به واقعیت تبدیل شده است. برای طراحی مگنت ابررسانای ایمن، آگاهی دقیق از فرایند گذار ابررسانایی به مقاومتی (فرونشانی) بسیار مهم است و معمولاً این گذار با قانون توان توصیف می‌شود. در این مقاله، پدیده‌ی فرونشانی و انتشار آن بر روی طول کوتاهی از نوار ابررسانای Bi-2223/Ag با به کارگیری پالس حرارتی موضعی و استفاده از شبیه‌س...
