The influence of Sm2O3 dopant on structure, morphology and transport critical current density of MgB2 wires investigated by using the transmission electron microscope

Table 2, Table 3 and Table 4 presents the lattice parameters results for undoped and doped MgB2 wires. The wires were made by using the powder-in-tube technique [1]. The results were published in an open access article. Fig. 1 The XRPD analysis for undoped and 2%Sm2O3 doped MgB2 wire with the density of 1.28 g/cm3 [1]. Fig. 2 The XRPD analysis for 2%Sm2O3 doped MgB2 wire with the density of 1.28 g/cm3 and 1.6 g/cm3 [1]. Fig. 13.
