One-pot synthesis and magnetic, electrical properties of single-crystalline α-MnS nanobelts

α-MnS single-crystalline nanobelts were synthesized for the first time on a large scale by solvothermal method in monosurfactant dodecylamine system. The investigation of magnetic properties shows antiferromagnetic transition temperature of as-synthesized α-MnS nanobelts is remarkably lower than that of bulk counterparts (152 K) and higher than that of corresponding nanoparticles (18 K). These single-crystalline α-MnS nanobelts exhibit higher coercivity (4013 Oe) than those of reported MnS nanowires (1020 Oe) and nanoparticles (330 Oe). The study on electrical transport shows that the conductivity of individual α-MnS nanobelt is as high as 3.2 × 10⁵ S/m.
