The internal friction (IF) of polycrystalline YBa~-'u307-x was studied from 4 to 300K for frequencies between 2 and 19 I-~ The samples were ]prepared by the standard solid state reaction method. The oxygen content was varied by annealing the samples in atr at various temperatures and subsequent cool

In this paper the critical density for a polycrystalline sample is calculated assuming a model of weakly coupled superconducting grains and the influence of grain size on the maximum tunnelling current is investigated. In addition the Josephson vortices are shown to be bound by the pinning force inh

Measurements of the trapped flux (rcmanent magnetism) in polycrystalline YBasCusO, in the range 15-50 K show that at low applied field pulses, flux is trapped in the intergrain voids. A detailed measurement of a map of the remanent field over the whole surface of the sample shows that at very low fi

Using a temperature measurement, the field induced dissipation in polycrystalline YBa2Cu30 x at T,~ T c has been measured for magnetic fields up to 2970 Oe applied at constant ramp rates, in the absence of a transport current. At 4.85 K results show that for H > 500 Oe the dissipated energy was rate
