“…This indicates that the amino acids have induced some disorder especially in the a-b plane of the structure and much less along the c-axis direction. A similar behavior of the lattice parameters is generally observed when MgB2 is formed in the presence of organic additives [49][50][51][52][53][54][55] and this is attributed to the substitution of carbon atoms on boron sites in the lattice. A decrease of the a-axis lattice parameter has also been detected in studies of Mg-deficient MgB2 [56][57][58].…”

“…Table 3 shows the lattice parameters and full width at half maximum (FWHM) values. These values of the h-BN doped samples are greater than those of the undoped sample, but the grain size and lattice strain values of doped samples are lower as in [38,39]. The average grain size of h-BN doped samples is calculated by using Scherrer-Warren formula [40];…”

The present study reports the effect of hexagonal boron nitride (h-BN) doping on the superconducting properties of bulk MgB 2 samples. Structural, electrical and magnetic properties of 3 wt% h-BN doped MgB 2 samples are studied in terms of three different sized h-BN nanoparticles. The results show that h-BN doping has no significant change on critical transition temperature (±0.5 K deviation), but decreases the magnetic J c with increasing the h-BN particle size. Among the doped samples, a highest J c (T = 10 K) value of 1.8 9 10 4 A/cm 2 is achieved for the sample doped with the smallest sized h-BN at zero external magnetic field but it is still lower than the 2.5 9 10 4 A/cm 2 obtained for the un-doped sample. In the scope of this study, it is investigated whether or not the nano-sized h-BN particle is a possible candidate to improve the pinning properties of the MgB 2 sample and we suggest that particle size is very important parameter in h-BN doping into MgB 2 .

“…The impact of BMT on the critical current density of glucose-doped MgB 2 superconductors was examined by Parakkandy et al [179]. To determine the ideal time for ball milling to get superior J c (H, T) in MgB 2 , the effect of BMT on the physical parameters was explored.…”

“…These liquid media promote homogenous mixing. Parakkandy et al [179] looked into how the magnetic and topological characteristics of MgB 2 made using a high-energy ball mill and sintered at a low temperature, were affected by the milling conditions. The purpose of this paper was to study, how the magnetic and surface topological properties of the produced MgB 2 were affected by dry and tolueneassisted milling.…”

Although the fascinating effect of superconductivity was discovered more than one hundred years ago, only a few low-temperature superconductors, especially Nb3Sn and NbTi, have reached everyday-life use. After the discovery of superconductivity in MgB2 in 2001, a boom appeared in interest in employing MgB2 in commercial applications, facilitated by simple crystallographic structure, high critical temperature, low-cost raw ingredients, simple and fast production, and other advantages for moderate temperature applications. It only lacks high flux pinning and good mechanical performance. In this review, the implications of manufacturing procedures on the superconducting properties, crystal and electronic structure of MgB2 are discussed. The advantages and drawbacks of various manufacturing processes will be presented, as well as the ways how to improve MgB2 superconducting performance. The impact of oxygen reduction, elements doping, the introduction of defects and additives, and the effect of precursor refinement on superconducting properties are here compiled to give an overview of the progress of flux pinning enhancement in bulk MgB2.
