Enhancement of total trapped fluxes on φ65 mm GdBaCuO bulk by multi-pulse techniques
抄録
We have investigated the total trapped flux ΦT(z) on the φ65 mm GdBaCuO superconducting bulk as a function of distance z from the bulk surface magnetized by a successive pulse field application (SPA) with identical magnitude and subsequent iterative pulsed-field magnetization method with reducing the amplitude (IMRA) at various temperatures Ts. The ΦT(z) value was enhanced by the IMRA process and reached 5.02 mWb on the bulk surface at Ts = 40 K, which was about 1.7 times larger than that at the end of SPA. The ΦT (4 mm) value at 40 K by the SPA+IMRA method was as high as (4 mm) by field cooled magnetization under Bex = 3 T at 48 K. The IMRA method is quite effective to enhance the ΦT value for large superconducting bulks.
