Hi Omar
Personally i had made an IR receiver trying to demodulate any possible useful frequency that might be imposed on it. I tried for demodulating frequencies in the KHz range (strong signals) that exist in the area but the result was very dissapointing. The IR field behaved like it is a total dc field with not any short of fluctuations. Despite the high amplification stage i never got any response.
I think that you should include in your research the diamagnetic property of the target.
