Experimental Analyses of Spike Domains in Stress-Coated Grain-Oriented Electrical Steels (GOES)

Year: 2026

Type: article

Abstract: Recent studies have revealed that spike domains can occupy a substantial fraction of the magnetic domain area in grain-oriented electrical steel (GOES), in some cases exceeding 30%. However, there is currently no established understanding of how spike domains influence the iron loss characteristics of GOES. To clarify this relationship, it is necessary to correlate local magnetic domain structures with corresponding local iron loss measurements. In this study, magnetic domain structures were observed using the Faraday effect, and local iron loss was measured with thermistors. By directly correlating these measurements, the influence of spike domains on iron loss was systematically investigated. The results indicate that the emergence of spike domains may contribute to a reduction in iron loss.
