Abstract
The glassy exponent mu of a melt-textured YBa2Cu3O7-x sample is derive d from measurements of the magnetic hysteresis loops with various appl ied field sweep rates and at different temperatures and magnetic field s. Thus, the dependences of the exponent mu on temperature and field a re obtained. Furthermore, we report for the first time the crossover-l ine of the vortex creep regime from a single vortex to a small bundle.
