Transmission Mössbauer Spectroscopy on Pulsed-Laser-Deposited Thick CoFe2O4 Films

57Fe Mossbauer spectra of pulsed-laser deposited (PLD) films of CoFe2O4 of 0.3 µm thickness is investigated using transmission geometry is reported. Mossbauer parameters were determined for the tetrahedral (A) and octahedral (B) sites. The PLD processed films gave measurable spectra with no visible evidence of clustering or multiple phases present. Results on the films agreed with those of the bulk material. The films exhibited magnetic hyperfine and quadruple splittings similar to that of bulk CoFe2O4. This work demonstrates that measurable transmission Mossbauer spectra may be obtained for PLD deposited CoFe2O4 thick films.
