Sounds like you may need a diffusion barrier (like Ni or Pt) to prevent
migration of the Gold.

I am depositing gold film (thickness 0.1 micron)by thermal evaporation on
oxides,
but when i am annealing my sample to 700K this gold film become non
-conductive may be duo to formation of gold oxide. But from
literature i found
that gold should not become oxide till 1200K. I also read people using
gold electrodes (thin film by thermal evaporation) on their samples and
work till 900k kindly let me know where i am doing mistake, wether to take
more thick film or something else.
