The highest coercivity Hc of 11.1 kOe was obtained for Sm(Fe0.8Co0.2)12-B thin fi lms with the thickness of 100 nm and B content of 11.2 at.%. From X-ray diffraction patterns, peaks from (002) and (004) of ThMn12-type phase were clearly observed for the fi lms. However, no significant improvement in magnetic properties was observed with the addition of C and N to the Sm(Fe0.8Co0.2)12 alloy, as was the case with the combined addition with B. It was confi rmed that only the addition of B contributes significantly to the improvement of magnetic properties from the result of adding light elements to this series of Sm(Fe0.8Co0.2)12 alloy.","PeriodicalId":36791,"journal":{"name":"Journal of the Magnetics Society of Japan","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73811840","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}

The noises from transformer cores seem to be mainly caused by magnetostriction. Thus, it is necessary to establish a method for quantitatively calculating the force generated from the magnetostriction (magnetostriction force) with not only high-accuracy but also high-speed. This paper presents that the magnetostriction force is calculated based on a reluctance network analysis (RNA) by using a simple-shape wound core as an object of discussion. The validity of the proposed method is indicated by comparing with calculation results obtained from a finite element method (FEM).","PeriodicalId":36791,"journal":{"name":"Journal of the Magnetics Society of Japan","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89837843","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}

Many researchers have studied novel magnetic materials, such as nanocrystalline magnetic materials (NMMs), for low-loss electric motors and transformers. This study experimentally examines the hysteresis ( B – H ) curve and iron loss properties of the NMM core excited using a pulse width modulation (PWM) inverter at high carrier frequencies on the order of MHz with and without the dead time. For comparison, the magnetic properties of amorphous magnetic materials (AMMs) core are also evaluated. Particularly at high carrier frequencies (approximately 1 MHz), the iron loss of NMM and AMM cores significantly depends on the dead time. Compared with the case of the AMM core, the NMM core suppresses the increasing rate of iron losses caused by the dead time because the area of minor loops in NMM becomes small, particularly in high-frequency regions.","PeriodicalId":36791,"journal":{"name":"Journal of the Magnetics Society of Japan","volume":"101 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80279647","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}

It was confirmed the isotropic SWs were refracted at a thickness step by following the Snell's law. We also found that the refraction angle of SWs of the dipole-exchange mode depends on the resonant frequency, indicating that the chromatic aberration effect should be taken into account in designing magnonic devices.","PeriodicalId":36791,"journal":{"name":"Journal of the Magnetics Society of Japan","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73285061","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}
