The nanoparticles were produced from a solution of zinc acetate dihydrate and manganese(II) acetate tetrahydrate using ethylene glycol

At present it is the leading

• hydrothermal and solvothermal synthesis [16][57]. The growing popularity of these methods is proved by the emergence of new types of reactors, e.g., microwave stop-flow and continuous-flow in supercritical water [57][58][59][60][61][62][63]. Microwave solvothermal synthesis (MSS) is quicker, purer, and more

Keywords: cobalt-doped zinc oxide; ferromagnetism; magnetic properties; microwave solvothermal synthesis (MSS); paramagnetism; Introduction Nanomaterials have drawn the attention of researchers from all over the world due to their new

• nanoparticles could be produced using microwave solvothermal synthesis (MSS) [68][69][70][71]. Magnetic investigations were performed to verify several points. First of all, we tested if uniform samples grown by a low temperature MSS process show paramagnetic response, as observed in ZnMnO systems [34]. Next
