Thermally activated flux motion is studied in proximity coupled multilayers, containing a number N of 24.~ thick DyBa2Cu307 layers separated by 96A (or more) of (Yi.xPrx)Ba2Cu307 alloy (x--0.4, x=0.55). In contrast to ultra-thin decoupled layers, for which we find that the activation energy for flux

The concentration dependence of the transition temperature T c has been studied in the high-T c compounds (Y~ xTlx)-Ba2Cu307 y, Y(Ba 1 xKx)2Cu307 y and YBa2(Cu I xMg~)307 y. In the TI-compound, the results show little effect on T C. In the K-compound, T~ gradually drops with increasing K concentrati
