GAPPED AMORPHOUS METAL-BASED MAGNETIC CORE

摘要

PROBLEM TO BE SOLVED: To provide a magnetic core having low magnetic permeability and exhibiting linear BH behavior.

SOLUTION: A magnetic implement has a gap size ranging from about 1 mm to about 20 mm. The magnetic implement has a magnetic core composed of an amorphous Fe-based alloy. A physical gap is provided in a magnetic pass of the core. The alloy having an amorphous structure is composed of the components (Fe-Ni-Co)-(B-Si-C). The sum of the Fe+Ni+Co content is in the range of 65 to 85 atom%. The core preferably exhibits overall magnetic permeability ranging from about 40 to about 200 and enhanced magnetic characteristics.
