摘要: Abstract The partial substitution of oxygen by fluorine, in magnetite, has allowed us to increase the concentration Fe 2+ ions and modify ratio ( 3+ ) oct. without introducing a foreign cation. Studies specific heat X-ray diffraction at temperatures near that Verwey temperature show crystallographic transformation is linked existence octahedral ions.
