Search the Hard Magnetic Tetrataenite Phase in the Fragments of Chelyabinsk Meteorite
Few Fe-Ni particles with composition close 50:50 were found by EDX and SEM investigations in the fragment of Chelyabinsk meteorite. These inclusions were extracted and magnetic domains were observed with the help of sol-gel method. No hard magnetic particles with tetragonal L10 crystal structure (tetrataenite) were detected.
