Abstract

We have studied the voltage noise Vnoise and the voltage noise spectral density Sv of YBaCuO superconductor in the regime of high magnetic field. Our measurements were taken for different temperatures covering the vortex-glass and vortex-liquid transition which represents the Tg temperature glass, The voltage noise spectral density Sv(f, T, H) as a function of frequency exhibits 1/f behaviour according to a lorentzian shape A((1+ ?f/f0)B)C, where the constants A, f0, B and C are all determined, and temperature has a strong influence. in addition, we study the variation in the velocity of the vortex as a function of temperature.
