Mössbauer spectra of chosen CoFe2O4 samples. Mössbauer spectra of CoFe2O4 educt (0 p) and products after first (1 p) and tenth (10 p) PLFL passage measured at room temperature (left), 4.3 K (center) and 4.3 K with an applied field of 5 T (right). The subspectra correspond to: Tetrahedral A-sites (green) and octahedral B-sites (blue) of CoFe2O4, superparamagnetic CoFe2O4 nanoparticles (magenta) and a presumable parasitic LDH phase (dark yellow).
