✦ Synopsis

Magnetization of a cylinder of bulk superconductor Bil.7Pb0.3Sr2Ca2Cu30 v, whose length had been shortened stepwise, showed that He1 was independent of cylinder length. Thus Mc~ was independent of the demagnetic factor, when the length of the cylinder was larger than the diameter however, H¢~ was dependent on the demagnetic factor, when the length was smaller than the diameter. The demagnetization factor was constant, ~¼ for /< d.

Hc2 measurement in high pulsed fields, of type II superconductors is described. A special pick-up is used to measure the induced dM/dt while, simultaneously, an operational amplifier gives the derivative of the differential susceptibility (DDS). The double peak signal obtained decreases with increas
