Abstract

A high-performance bench-top cylindrical magnetic shield made of amorphous ribbons is presented. It has double active shells made of Metglas 2705M amorphous ribbon to which magnetic shaking enhancement is applied. Passive shells made of Metglas 2714A amorphous ribbons were installed to reduce leakage field of magnetic shaking. With total weight 1.3 kg of the amorphous ribbons, sufficiently large shielding performance was measured against 10-μT, 10-Hz uniform magnetic field. The value of axial shielding factor (ASF) was 700 and transverse shielding factor (TSF) was more than 20 000. The residual dc fields were less than 20 nT in axial direction and 5 nT in radial direction under the worst condition, where the shield axis is oriented along the horizontal component (∼ 32 μT) of the Earth's magnetic field.
