Eddy current losses were calculated on the basis of the dynamic domain behavior using two models. a modified Pry and Bean model, and a model which considers the difference between each domain wall velocity. Both models assume sinusoidal domain wall motion. The measured eddy current losses were compared with calculated values. However, the measured losses disagreed with estimations in the frequency range from 50 to 500 Hz. The domain wall motion in each layer was estimated from the flux voltage waveform of a movable pickup coil inserted into a layer of a 3% Si-Fe strip. We found that the voltage waveform was not sinusoidal even if the secondary voltage waveform of the core was sinusoidal, and that the magnitude of the voltage in each layer was not uniform. The results mean that the domain wall motion is not uniform even in the 50 to 500 Hz range. The nonuniformity of the domain wall motion makes the eddy current losses larger than the results estimated on the basis of the two models.","PeriodicalId":100647,"journal":{"name":"IEEE Translation Journal on Magnetics in Japan","volume":"9 6","pages":"261-266"},"PeriodicalIF":0.0,"publicationDate":"1994-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/TJMJ.1994.4565990","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67872878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TEM observations revealed that nitrided films are composed of heterogeneous phases with a very fine network structure. It was found that the properties of films are determined mainly by the combination of the Al and N concentrations. The coercivity of films containing more than 10 at% Al decreases with increasing N content, even when the film thickness is more than 2 μm. A steep increase in the electrical resistivity and a slight decrease in the magnetization of films containing more than 15 at% Al were observed during the initial increase in the N concentration, and both electrical resistivity and magnetization decreased rapidly when the N concentration was the same as that of Al. These anomalies are attributed to intergranular materials, indicating the presence in these films of a phase rich in Al and N.","PeriodicalId":100647,"journal":{"name":"IEEE Translation Journal on Magnetics in Japan","volume":"9 6","pages":"138-145"},"PeriodicalIF":0.0,"publicationDate":"1994-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1109/TJMJ.1994.4565971","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67872979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
