<Chemistry id="chema01" num="0001"><Image id="ia01" he="8" wi="50" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein x < 20 atomic%, 7 atomic% ≦ y < 35 atomic%, 7 atomic% < x+y s 35 atomic%, 0.1 atomic% ≦ z ≦ 3 atomic%, and 0.01 ≦ a ≦ 0.1. The fine amorphous metallic wire has low magnetostriction, high magnetic permeability, high saturation magnetic flux density, and excellent toughness, and is stable against a bias magnetic field. Hence, it can be used as a material for electromagnetic devices such as a coordinate reading device, a current sensor, an eddy current sensor, a magnetic sensor, or a displacement sensor.</p> |
