Strontium hexaferrite platelets: a comprehensive soft X-ray absorption and Mössbauer spectroscopy study
Platelets of strontium hexaferrite (SrFe12O19, SFO), up to several micrometers in width, and tens of nanometers thick have been synthesized by a hydrothermal method. They have been studied by a combination of structural and magnetic techniques, with emphasis on Mössbauer spectroscopy and X-ray absor...
