Abstract
The high-T-c (Eu1-xGax)Ba2Cu3O7-delta superconductors with x = 0, 0.01 , 0.02, 0.03, 0.06 and 0.09 were synthesized by a ceramic technique. T he gallium concentration dependence of the lattice parameters was dete rmined. A transition from orthorhombic toward tetragonal structure was relevated for the most gallium concentrated sample. The temperature d ependence of the magnetic susceptibility pointed out the diamagnetic t ransition at 78 and 80 K. In the paramagnetic region the magnetic susc eptibility exhibits anomal temperature dependence.
