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

β¦ Synopsis
The pulsed field apparatus of the Maspec Institute is introduced. A new induction method of measuring upper critical tield (HL,) in type II superconductors is prcacnted; its princtple is hased on the derivative of the pick-up output signal The new method is compared with others that art' now widely used. An example of flL, in the high 7'L superconductor YRa2Cu,0_ at 78 K is given
