Abstract

An unusual form of superconducting transition has been observed in some of the superconducting compounds L2-xMxCuO4-y (L=Pr,Nd,Sm,Eu; M=Ce,Th) under low magnetic fields. When the temperature is reduced below the critical one, the samples resistance first increases, then drops to a nonzero value, increases again, and finally decreases at low temperature, creating a characteristic double-peak transition. The behavior is explained in terms of intra- and intergranular superconducting transitions.
