It calculates the electromagnetic force on individual stator teeth by the Maxwell stress method, based on 2-D finite element analysis of the electromagnetic field.

The method has been validated experimentally and used to predict the vibration of various PM brushless motors with different fractional slot/pole number combinations, such as 9/6, 12/8, 15/10, 12/10, 18/6, etc., on both no load and on load.","PeriodicalId":262607,"journal":{"name":"INTERMAG 2006 - IEEE International Magnetics Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121461102","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}

All models, however, emphasize the importance of Fe-Pt coordination and the induced moments in Pt-atoms for the magnetic anisotropy and the formation of an effective exchange field. We recently performed XMCD measurements on a Fe50Pt50 monolayer alloy grown on vicinal Pt(997). The surface alloy exhibits high coercive fields comparable to those found in 3D samples exhibiting L10 structure. These results suggest that, in contrast to theoretical work, the third dimension in the L10-phase is not necessarily the key for the understanding of its hard magnetic properties. We therefore studied the magnetism of low-dimensional Fe structures as a function of Fe-Pt as well as Fe-Fe coordination.","PeriodicalId":262607,"journal":{"name":"INTERMAG 2006 - IEEE International Magnetics Conference","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132411772","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 iron-oxides have significantly different magnetic properties. Thin film bilayers were deposited using a dual ion-beam deposition technique that produced an antiferromagnetic iron-oxide layer composition that ranged from Fe3O4 to Fe2O3. The crystal structures of the Fe-oxide films were characterized by X-ray diffractometry (XRD). A JEOL (JEM-2010) Transmission electron microscope (TEM) operating at 200 kV was used for microstructural analysis. The magnetic properties such as exchange coupling and magnetic hysteresis of these bilayers were characterized using a vibrating sample magnetometer (VSM) and a superconducting quantum interference device (SQUID) magnetometry.","PeriodicalId":262607,"journal":{"name":"INTERMAG 2006 - IEEE International Magnetics Conference","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129966622","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}
