Applications of the hybrid shielding in biomagnetometry

Abstract

The work presents the experimental results concerning the electromagnetic characteristics of a shielded room destined to bio-electromagnetism researches and to the utilization of a high resolution SQUID magnetometer. The experimental results regarding the dependence of the shielding factor on the applied field frequency are presented. The phase of the residual magnetic field and its dependence on the frequency of the external field has also been determined. The experimental results confirm the theoretical studies on the utilization of the non-ferromagnetic material shields.
