Controlling structural and magnetic properties of SrFe12O19 nanoplatelets by synthesis route and calcination time

[EN] Nanocrystalline platelets of Sr hexaferrite, SrFe12O19, were prepared by four techniques (two hydrothermal and two sol–gel techniques) and calcined at 1000 ◦C for 1, 2, 4, 8 and 16 h. The microstructure of these samples was analyzed using Rietveld refinements of high-resolution synchrotron powd...
