“…The control of crystal structure and microstructure by applying various synthesis methods e.g. microwave [19,63], sol-gel [7,44,49,56,74,88], self -combustion [7,10,24,36,49,51,52,56,74], hydrothermal precipitation [4,20], mechanical alloying [28,35,53,54], solvothermal [5,60], coprecipitation [6,39,46,48,49,69,73,76] and others [14,15,22,23,[25][26][27]29,34,43,67,77,89,90] allows to design and produce nano ferrites without drawbacks typical for their bulk counterparts [21]. The applied type of confinement leads to various properties typical...…”
