Magnetization versus applied field data have been taken up to 5 T over a wide temperature range from 10 K to 77 K for polycrystalline YBa,Cu,O, with x=6.98 and x=6.62. The intragrain critical current density has been calculated based on the magnetization measurements. The observed temperature depend
The intragranular critical current density JΒ’, the apparent pinning potential U0, and the irreversibility temperature Ti~ of meltgrown (MG), quench-melt-grown (QMG), and sintered YBa2Cu306Γ·y (123) were studied. A systematic increase in Uo and a slower drop in Jc with temperature and magnetic field h
