First, the magnetic circuit model considering the magnetic hysteresis behavior is derived. Next, this magnetic circuit model is developed to the reluctance network model, to analyze more complicated devices such as an electric motor. Furthermore, this magnetic circuit model is improved to take the dynamic hysteresis characteristics including the skin effect into account. Finally, the prediction method of the deteriorated hysteresis loops in core material due to machining process is established.","PeriodicalId":36791,"journal":{"name":"Journal of the Magnetics Society of Japan","volume":"145 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74030635","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}

In this study, we propose a quantitative measurement method for three dimensional (3D) magnetic field vector measurements. The x- and y-components of the magnetic fields within the measured plane are calculated from the measured z-component by using a signal transformation method based on magnetic field transfer functions. Furthermore, the magnetic field distributions at different heights are also obtained from a one-shot image. In this paper, 3D magnetic field vector measurements are demonstrated for ferrite magnets and an electrical steel sheet.","PeriodicalId":36791,"journal":{"name":"Journal of the Magnetics Society of Japan","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77882891","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}

However, there remain many unidentified bands. Our previous paper revealed that single void-defect induced graphene molecule reproduce many astronomical bands. In this paper, we investigated a series of multiple-void induced graphene molecules. We tried spin dependent DFT calculation. Model molecules are C 23 (one carbon pentagon ring among hexagon network), C 22 (two), and C 21 (three). Those were all magnetic molecules with spin state of Sz =2/2, 2/2 and 4/2 respectively. Calculated IR was compared with astronomical observation. The largest astronomical band at 18.9 micrometer was found in C 23 . Second largest band at 17.4 micrometer appeared both in C 22 and C 21 . Other major bands from 6 to 10 micrometer were reproduced well by a combination of C 23 , C 22 and C 21 . Similarly, larger size graphene molecules of C 53 , C 52 and C 51 were also magnetic and reproduced astronomical bands as well. Weighting sum IR of those molecules could successfully trace astronomical 12 bands from 6 to 20 micrometer.
