Interest of the biomagnetic fields results from necessity of the using of non-invasive methods of early diagnosis of many diseases like heart attack, cerebral stroke, tumours. The magnitude of the induction of the biomagnetic fields values are in the range of 10 fT- 50 pT. SQUIDs can register the magnetic field of the induction as low as even 0,1 fT. The fundamental condition of the practical application of SQUIDs is preparation of the shields, which would protect a subject against the electromagnetic smog (the average magnitude of the magnetic induction - about 50 µT). Theoretically, magnetic field oughtn't to penetrate into superconducting materials only. Because this material must be continuous (without cracks), so it seems that only superconducting layer shields can fulfil this condition. This paper shows preliminary results of investigation on synthesis of superconducting YBCO layers by the MOCVD method on dielectric substrates.
