Magnetic hysteresis measurements have been made on a variety of YBa2CuaO74 samples (sintered, flux grown crystalline and melt grown materials). Claims that the unusual behaviour of the hysteresis of single crystals is caused by inhomogeneities and oxygenation, have been investigated. It has been fou

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
The critical current and flux pinning properties of melt grown YBa2Cu3OT\_6 bulk material were investigated by transport measurements and V-I characteristics. A JΒ’ of 16 000 A cm -2 in zero field and 3000 A cm -2 in 1 T at 77 K was obtained using a criterion of 3.3 I~V cm-~. No features of granulari
