Abstract
The glassy exponent Μ of a melt-textured YBa2Cu3O7-x sample is derived from measurements of the magnetic hysteresis loops with various applied field sweep rates and at different temperatures and magnetic fields. Thus, the dependences of the exponent Μ on temperature and field are obtained. Furthermore, we report for the first time the crossover-line of the vortex creep regime from a single vortex to a small bundle.
