Abstract
Using the floating zone melting technique Bi(2)Sr(2)CaCu(2)O8+delta sa mples were prepared. The variation of pulling rate gives the possibili ty to change the grain size and texture of the sample. The critical cu rrent density j(c) dependences on magnetic field and temperature have been studied. It was found that for large magnetic fields the j(c) val ue is highly dependent on the magnetic field sweep rate dH/dt. The uni versal scaling behavior j(c)(H, dH/dt, T) has been observed.
