Jy. Park et al., THE EFFECT OF MAGNETIC-FIELD ANNEALING ON MAGNETIC-PROPERTIES IN ULTRATHIN FE-BASED NANOCRYSTALLINE ALLOYS, IEEE transactions on magnetics, 33(5), 1997, pp. 3799-3801
Ultrathin Fe78Al4B12Nb5Cu1 and Fe83B9Nb7Cu1 nanocrystalline ribbon all
oys below 10 mu m in thickness were annealed in transverse magnetic fi
eld, and then the high-frequency soft magnetic properties and their co
mpositional effect were investigated. Very high effective permeability
and excellent magnetic core loss characteristics in MHz range were ob
tained for both alloys after optimum annealing. However, the Al-added
alloy was more sensitive to the magnetic field annealing and much impr
oved soft magnetic properties in the high frequency range were reveale
