MAGNETIC COMPOSITE ARTICLE AND MANUFACTURING METHOD OF THE SAME, AND SOFT MAGNETIC POWDER OF FE-AL-SI SYSTEM ALLOY USED IN THE COMPOSITE ARTICLE

摘要

SOFT MAGNETIC POWDER OF FE-AL-SI SYSTEM OF WHICH MAGNETOSTRICTIVE CONSTANT l TAKES A POSITIVE VALUE AT THE ROOM TEMPERATURE IS EMPLOYED TO PRODUCE A MAGNETIC COMPOSITE ARTICLE SO THAT A TEMPERATURE CHARACTERISTIC OF CORE-LOSS OF THE ARTICLE TAKES A NEGATIVE VALUE AT THE ROOM TEMPERATURE. EXCELLENT MAGNETIC CHARACTERISTICS SUCH AS A LOW CORE-LOSS AND A HIGH PERMEABILITY CAN BE OBTAINED AT A HIGH FREQUENCY BAND.FIGURE 1
