“…La358 superconductor exhibited larger lattice parameters, which led to a larger cell volume (see Table 1). The increase in the c parameter confirms that the distance between the CuO chains is affected by the ionic radius (Sm 3+ = 1.04 Å and La 3+ = 1.16 Å), such as was previously reported 4,27 .…”

“…The YBCO family of superconductors is constituted by the materials YBa 2 Cu 3 O 7-δ (Y123) with a critical temperature (T c ) of 90 K 1,2 , YBa 2 Cu 4 O 8 (Y124), Y 2 Ba 4 Cu 7 O 15 (Y247) and Y 3 Ba 5 Cu 8 O 18 (Y358), which differ on the number of CuO 2 planes and CuO chains 3 . These superconductors have electronic and magnetic applications, such as electric motors, particle accelerators, magnetic levitation devices, and cables 4 .…”

In this paper, the synthesis of the La 3 Ba 5 Cu 8 O 18-δ and Sm 3 Ba 5 Cu 8 O 18-δ superconductors using the combustion method is reported for the first time. Besides, a comparison with the solid-state reaction method was performed. The materials were synthesized at 870 °C for 24 h under oxygen flow. Rietveld refinement showed materials with the main crystal phase corresponding to the orthorhombic structure of space-group Pmm2 (25), with purity in the range 51-85%, which had not reported for the RE358 systems. On the other hand, the magnetic measurements under external fields (30 and 100 Oe) confirmed the diamagnetic response associated with the Meissner effect, and T c values between 24 and 58 K.
