Abstract :
The magnetic properties and features of magnetic domain structures of newly developed grain-oriented 15-50 μm thickness 3% Si-Fe with very high permeability were investigated. The induction of these materials was 1.70-1.95 T at 800 A/m. These high inductions developed low core losses. The losses of toroidal cores made of 50 μm thick material were W15/400=8 W/kg. Despite very small primary recrystallized grain size, they consist of simple magnetic domains with 180° domain walls and ac magnetization is achieved by simple main domain wall displacement
