Thin grain-oriented silicon steel sheets have the lowest iron loss at a thickness of 30 µm. We observed the recrystallization behavior and magnetic properties of 30 µm thick silicon steel sheets, and compared the results with those of 60 µm thick ...

A thin oxide layer with the effective thickness of about 150 nm was prepared on a surface of a thin Co-based amorphous ribbon by acid-treatment followed by annealing, and magnetic properties of cores made of it were studied. The oxide layers incre...

We investigated the effect of rolling conditions on the textures and magnetic properties in order to advance the reduction of iron loss in thin grain-oriented silicon steel sheets which can be produced by using the three-stage rolling method. In t...
