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

sgy NMR has been used to study the effect of a range of substitutions (V, Fe, Co, Ni, Zn, AI and Ga) for Cu in YBa2(Cut\_xMx)~OT. A different behaviour is observed for the substitutions (Fe, Co, Ai and Ga), which go into the chain site and change the structure to tetragonal, compared to the other su
