Thin films of lithium ferrite (Li 0.5 Fe 2.5 O 4 ) have been deposited on (001) Al 2 O 3 by pulsed laser deposition, with substrate deposition temperatures ranging between 500 and 800°C, and oxygen pressures between 1×10 −1 and 4×10 −7 mbar. X-ray diffraction shows that films grow with a (111) orientation. Conversion electron Mössbauer spectra...
