Vortex dynamics in (Tl,Pb)(Sr,Ba)2Ca2Cu3Oy single crystal

Journal Article


Abstract


  • Magnetic moment measurements performed on a single crystal sample of (Tl,Pb)(Sr,Ba)2Ca2Cu3Oy reveal an increase in magnetic

    moment at intermediate fields. Magnetic hysteresis (mH) loops were taken at different constant temperatures using either a MPMS-

    5T SQUID magnetometer or a PPMS-9T magnetometer and within the temperature range 0.1 < T/Tc < 0.85. Vortex dynamics at fields

    below the peak in hysteresis loops for the sample is shown to be well explained by a quasi-lattice Bragg glass state and elastic collective

    vortex creep.
