Two sets of Sr₂FeMoO₆ thin films were prepared with pulsed laser deposition and the effect of the laser
fluence and the deposition temperature was investigated. The Sr₂FeMoO₆ thin films showed clear evi-
dence of impurity phases when the laser fluence was altered. Phase pure films resulted through the
whole temperature range between 900 ^◦C and 1050 ^◦C when a proper laser fluence was used. Films fabri-
cated at lower deposition temperatures resulted with smaller surface roughnesses around 5 nm, higher
Curie temperatures and with relatively high saturation magnetization values. The Curie temperature
was determined from the minimum of the first order derivative and results showed the highest values of
350 K and above. The films with the highest Curie temperature reached zero magnetization above 400 K.
The results indicate that both high microstructural and high magnetic quality Sr₂FeMoO₆ thin films can
be obtained with a deposition temperature between 900 ^◦C and 950 ^◦C. This provides better fabrication
parameters for the upcoming SFMO multilayer structures.
